Handles and Hot parts
The following points become hot during and soon after measurements.
Other precautions
• When the drying temperature is set to 200°C, the thermostat may cut the power of the halogen lamp
after 30 minutes. The next measurement can be started only when the halogen lamp has cooled down.
• When a measurement time exceeds one hour, the maximum temperature is automatically regulated
down to 160°C for safety.
• During measurement, the STOP key is always effective. If there is an error or danger, press the STOP key.
• Turn the power switch off immediately should the sample catch fire.
For accurate measurement
• The working place for the analyser should be solid and free from vibration, drafts and as level as possible.
• Install the analyser where it is not affected by heaters, air conditioners or air flows.
• Keep the analyser away from equipment that generates magnetic fields.
Pre-treatment of sample
• Break grain samples into small, uniform pieces this will avoid explo-
sion and help the drying process.
• Spread the sample on sample pan as evenly as possible.
• Apply an optimal sample weight. If the sample weight is too small,
precise results may not be possible.
• To repeat measurements, keep the same sample weight.
• It is highly recommended to pre-heat the analyser before the first
sample measurement.
• Place the sample only on a sample pan kept at room temperature. When a sample is put on a hot
sample pan, results may be errertic.
• The glass fibre sheet (accessory AX-MX-32) is availble for measurement of liquid samples.
Calibration sample (Sodium tartrate dihydrate, Na2C4H4O6•2H2O )
• Use the calibration sample to check the analysing process and accuracy of the analyser.
Sodium tartrate dihydrate contains a theoritical moisture 15.66% in the molecule. However, the cali-
bration sample may absorb ambient moisture and show higher, up to 0.09%, moisture content above
it`s theorical value.
• Recommended measurement for the calibration sample is followed by preheating process of 8 min-
utes at 160°C, set the condition to 160°C, MID. in standard mode. Sample volume is 5g. The result is
usually between 15.50 % and 16.00 %. Refer to "Select a Unit" of section 7.2.
• The same calibration sample can not be used again.

• The moisture analyser MX-50 and MF-50 are built using a super hybrid sensor (S.H.S.) originaly
designed for high resolution laboratory balances. Therefore, the result is more precise and reliable.
• An analyser with S.H.S. needs a sample mass of only a few grams and this makes the measurement
time shorter.
• A 400W halogen lamp is used as the heating source and the temperature on the sample pan may
reach 200°C in as quick as two minutes.
• The Standard Mode (Refer to section 7.1) can easily provide the moisture content at high accuracy
automaticaly using pre-set conditions.
• There are three User Modes that the user can quickly set their own measurement parameters.
Automatic mode When the Drying Rate (change of moisture content per unit of time %/s) becomes
less than the preset value, the measurement will be automatically completed.
Timer mode The sample is dried for a preset time period.
Manual mode This user can terminate the measurement by pressing the STOP key.
• The analyser can store and recall individual measurement settings. Maximum numbers of setting
stored in the analyser differs by model.
Maximum number MX-50 20 sets
MF-50 10 sets
• The Data Memory can store measured results and can transfer the data to PC or a printer at a later
time. Maximum numbers of data possible, stored in the analyser, differs by model.
Maximum number MX-50 results of 100
MF-50 results of 50
• The software "WinCT-Moisture", an accessory of the MX-50, has 3 separate software programs
– RS Key can allow data from the moisture balance to be placed into any Windows based program.
– RS Com can allow the remote control of the analyser from a PC and will record data into it’s own
text sheet.
– RS Fig can graphically show the change of moisture content and other information to a connected
PC in realtime.
• The software "WinCT", an accessory of the MF-50, has 2 software programs RS Key and RS Com as
described above.
• The analyser is equipped with a serial interface as standard for connection to a printer or a PC.
• The calibration of the weighing part of the analyser can be adjusted using calibrated weights.
• The temperature calibration of the MX-50 can be adjusted using the dedicated temperature calibrator
(AX-MX-43).
• The analyser can output GLP, GMP and ISO compliant data to a printer at the end of either calibration
process.
• The analyser has a self test function that can detect functional errors.
• The analyser displays the Drying Rate, [%/ min], during measurement. It can be used as a reference to
find suitable analysing modes.
• Sample pans can be used repeatedly if traces of the previous sample are completely removed.
• A calibration sample of Sodium tartrate dihydrate is supplied as a standard accessory to check the
function and accuracy of the moisture analyser.
• A reference card can be found underneath the analyser for quick reference.

7.1. Measurement Condition
The Analyser provides one Standard Mode and three User Modes with pre set measurement conditions.
List of Measurement Conditions
* When measurement is started and it passes one hour, maximum
temperature is automatically regulated to 160°C for safety.
Drying Rate: Change of moisture content per unit of time.
Example of standard mode
Unit Chart:
Display Data Formula Unit
Moisture content is based on W. *1(W - D) / W x 100 % MOIST/W
Moisture content (Atro) is based on D. *2(W - D) / D x 100 % MOIST/D
Solid D / W x 100 % RATIO D/W
Ratio *2 W / D x 100 % RATIO W/D
Gram value G
W: Wet sample mass D: Dried sample mass
*1: Factory settings
