1. GENERAL INFORMATION
1.1 INTENDED USE
The moisture analyzer isdesigned to verify relative moisture content insmall samples ofvarious
substances, dry mass content in small samples, and determine the mass ofweighed objects. Any
other use of the moisture analyzer may be dangerous bothtothe device and the user. The device
ensures a fast and precise determination of water content in a tested sample, and the touch screen
display considerably simplifies the operation and improves the functionality of the moisture analyzer.
The device can be used todetermine humidity content of different materials.
At the initial stage of the measurement, the moisture analyzer precisely determines the mass of an
object placed on the weighing pan. Asthe mass reading is stabilized, the sample is quickly heated
by the halogen lamp or IR emitter, causing water to evaporate from the sample. While sampling, the
moisture analyzer is continuously checking loss ofmass, and on completing this calculation, it
displays the current moisture content ofthe sample being tested.
Compared toconventional methods ofhumidity content determination of various substances, the
moisture analyzer considerably shortens the measurement time and simplifies the testing
procedure. The moisture analyzer allows users toset multiple parameters that influence moisture
content determination in a sample (temperature, time, drying modes, etc.).
!The moisture analyzer should be utilized and supervised only byusers who are trained and
experienced in these types ofinstruments. Do not make any design modifications. Additional
equipment compatible with the moisture analyzer and spare parts should be supplied by
Cole-Parmer.
1.2 WARNING SYMBOLS AND SIGNALS
Safety precautions are marked with special descriptions and warning signs. They warn a user of
possible dangers. Ignoring the safety warnings may cause injuries, damage to the moisture
analyzer, incorrect operation, and errors of measurements.
Warning Descriptions

1.3 SAFETY PRECAUTIONS
WARNING! The use of the moisture analyzer regardless of both, safety information and
service manual guidelines may cause health damage and even death.
WARNING: Nominal voltage for a moisture analyzer is 110V AC. It means that safety
usage precautions for low voltage devices must be abide by while operating the
device. Three-core power supply cable with grounding pin comes standard with a
moisture analyzer. If necessary, an extension cord can be used as long as it meets
the applicable standards and has a protective ground conductor. Intended
disconnection of the grounding cable is forbidden.
Voltage range for moisture analyzers marked with AC 110V symbol: 100 V–120 V,
50/60 Hz
CAUTION: The drying chamber cannot be opened during the drying process. The
halogen lamp and its glass shield may reach temperatures up to 400˚ C.
When setting up the moisture analyzer, leave enough space to prevent heat from
building up and to keep your analyzer from overheating. Leave about 20 cm around
the instrument and about 1 m above. Air vents located in the housing cannot be
covered, sealed, or blocked in any other way.
Do not put any flammable substances on, under or near the moisture analyzer. Be
particularly careful when removing the sample from the drying chamber. The sample
itself, the drying chamber, the shields, and the pan can still be extremely hot.
For any maintenance work such as cleaning the inside of the drying chamber, the
moisture analyzer must be switched off. Wait until all the components have cooled
down. Do not perform any modification to the heating module.
Some types of samples require taking particular safety precautions.
Some samples can pose a danger for people and objects. It is always the user who is liable for
possible damages caused by the use of an inappropriate sample.
CAUTION:
Corrosion can come from substances that release aggressive vapors (e.g., acids)
during the heating process. While drying such substances, it is recommended that
users work with small samples. Otherwise, vapors can condense on cold housing parts
and cause corrosion.
WARNING:
Fire or explosion can result from flammable or explosive substances, substances
containing solvents, or substances releasing flammable or explosive gases or
vapors. When in doubt, characteristics perform a risk analysis with the sample before
carrying out the procedure. For these samples, apply as a low drying temperature as
possible to prevent flames or explosion. During the analysis, it is necessary to wear
protective glasses and gloves. The samples should be relatively small. Under no
circumstances can the instrument be left unsupervised!
WARNING:
Caustic or corrosive components in substances that release toxic gases or vapors
can cause irritations of the eyes, skin, or respiratory system, illnesses, or even death.
Dry such substances only in fume cupboards.

3
Under no circumstances should the instrument be used within an area near potential
explosions.
The moisture analyzer is designed to be operated outside hazardous areas exclusively.
Do not open the drying chamber during the drying process. The moisture analyzer features a
halogen lamp or IR emitter, which are very powerful heat sources. Pay special attention not to touch
those elements of the moisture analyzer that get hot while the drying procedure (i.e., the disposable
pan, the pan handle, and the inner shields of the drying chamber).
1.4 GOOD WEIGHING PRACTICE
CAUTION!
!Do not open the drying chamber during drying process. Moisture analyzer features a IR
emitter or halogen lamp which are a very powerful heat source. Thus, operator should pay
special attention no to touch those elements of a moisture analyzer that get hot while drying
procedure (i.e.: disposable pan, pan handle, and inner shields of the drying chamber).
Remember that some of tested samples may become dangerous if heated (appearance of
poisoning vapors, danger of ignition or explosion).
!Lab Society moisture analyzer is not intended for dynamic weighing. Even if small amounts
of a sample are added to or taken off the weighing pan, the mass readout should only be
taken on stabilization of measurement result (upon displaying pictogram).
!Do not place any magnetic materials on the weighing pan. This can cause damage of the
measuring system of the instrument.
!Be sure to avoid impact shock and overloading the moisture analyzer in excess of the
prescribed maximum measuring range (max capacity), minus any possible tare weight that
has been applied.
!Never use the moisture analyzer in an environment endangered by explosion!
!This moisture analyzer is not adjusted for operation in explosive areas. There must not be
any modification made to the moisture analyzer.
1.5 SYSTEM PRECAUTIONS
Lab Society moisture analyzer adheres to all binding safety regulations. Nevertheless, there are
exceptional circumstances that may cause danger.
Do not open the instrument’s housing. Inside there are no parts that would require maintenance,
repair or replacement carried out by an operator. In case of any problems, contact Schuler Scientific
service ([e-mail] )
Use the device only as intended. Follow this user manual in terms of installation and configuration
of the device.

Since use of the moisture analyzer conversely to safety precautions and service manual guidelines
may be hazardous to operator’s health and life, it is obligatory to read them carefully:
!Use the moisture analyzer to determine humidity content in samples and to determine
mass of a tested sample; any other use of the moisture analyzer may be dangerous both
to the device and the operator,
!Before commissioning the moisture analyzer, make sure that the nominal power of the
device specified on its data plate is compatible with the supply in the mains to which the
moisture analyzer is to be plugged in,
!Halogen lamp and IR emitter can only be changed by an authorized service
employee,
!Protect moisture analyzer against contacts with liquids, it might lead to electrocution, fire,
emission of substances containing toxic or caustic vapor, emission of explosive
substances.
1.6 SUPERVISION OVER METROLOGICAL PARAMETERS
Metrological parameters of the moisture analyzer need to be checked by a user at regular
intervals.
Inspection frequency depends on the ambient conditions in which the moisture analyzer is
used, the types of processes performed, and the adopted quality management system.
1.7 STAFF COMPETENCE
The moisture analyzer should be utilized and supervised only by users who are trained and
experienced in such type of instruments.
In order to use the moisture analyzer, first read the service manual. Keep these instructions for the
future reference.
Do not make any design modifications. Additional equipment compatible with the moisture analyzer
and spare parts should be supplied by Spectrum Chemica or an authorized distributor.
1.8 MOISTURE ANALYZER MEANS OF OPERATION
For measurement temperatures ranging from 161°C to 250°C the time of maintaining the
temperature during the measurement is estimated proportionally, ~15 hours for 161°C – 10 min
for 250°C.
For a drying process carried out in 250°C, Max temp is maintained for 10 min, next the
program automatically lowers the temperature (drying is not interrupted) to 160°C.
Lowering temperature to 160°C takes ~10 min.
For FAST drying mode Max drying temperature re-manipulation is 30% but no more than Max
temperature for a particular moisture analyzer.

5. SAMPLES PREPARATION
This section of the user manual contains information about obtaining optimum test results during drying
process. There are hints for selection of appropriate drying parameters for various materials and
substances.
5.1 MOISTURE CONTENT MEASUREMENT ON A MOISTURE ANALYZER
Measurement ofmoisture content ina tested sample is performed by determining the loss of mass
in a sample by its heating (humidity evaporation).
The moisture analyzer has two components: a precision balance and a drying chamber.
Compared to standard moisture content determining methods, measurements with a Cole-Parmer
moisture analyzer are much quicker and do not require additional mathematical calculations (the
result of moisture content ispreviewed on an ongoing basis during product testing process).
Independent of the moisture content determination method, measurement accuracy ishighly
influenced by means of sample preparation and selection of testing parameters, such as:
•Sample size
•Sample type
•Drying temperature
•Drying time
In practice, the measurement accuracy is not as important as the speed of obtaining a
measurement result (control over technological process). Thus, heating a sample with the halogen
filament by the moisture analyzer makes the measurement process very time efficient.
Measurement speed can be additionally increased by adjusting the moisture analyzer’s parameters
depending on the tested substances.
Optimum temperature and drying time depend on sample type and size, as well as anticipated
measuring accuracy. The selection of drying parameters can only be performed on the basis of test
measurements.

5.2 SAMPLING AND PREPARATION
The sample’s features, its preparation and its size are very important factors influencing the speed
and accuracy of the measurement process.
The means of sampling and preparation are extremely important for repeatability of measurement
results, as a sample should be a representative part of the tested substance.
The final measurement result is vastly conditioned by precise and considered sample preparation.
A sample used for analysis has to represent the total structure of the tested material. The sampling
process should determine the sampling means, sample disintegration, particle size after
disintegration, sample uniformity and other. The sampling process should be completed as quickly
as possible so that a sample does not lose or absorb humidity from the surrounding area.
Applied sampling standards should match individual user needs as well as the requirements of the
tested material, its consistency and its sample size.
Number of samples
Increasing the number of tested samples also increases the statistical measurement certainty.
The number of samples depends on the uniformity of tested material, its purity, the accuracy of
applied measuring method and the anticipated accuracy of obtained results.
Mechanical disintegration of the material intended for measurement
The applied reducing method should be selected appropriately for the tested material.
Substances that are hard and brittle can be cut. Grinding such substances may cause them to
heat up and result in humidity vaporization, resulting in unreliable measurement results. Unless
a substance can be prepared for measurement in a way besides grinding, any possible moisture
content loss should be calculated.
Use of high-silica sand
Ensuring optimum substance drying requires that a sample has the largest possible surface for
moisture content evaporation. Test results of moisture content for substance with a glossy
surface (e.g., glucose syrup) or with a sheen (e.g., butter) can be much more reliable if the
sample is mixed with a dried high-silica sand to improve the measurement’s accuracy and
repeatability. While using the mixture, a disposable weighing pan with extended brim must be
applied to hold a greater volume of the sample.
Grease in a form of paste or melting substances
Such substances require testing with use of a filter made of glass fiber, which considerably
increases the active evaporation surface by separating the substance between the fibers.
