2 Safety Instructions
•Read this instruction manual before using the portable density meter SBS-3500.
•Follow all hints and instructions contained in this instruction manual to ensure the correct use
and safe functioning of the SBS-3500.
Liability
•This instruction manual does not claim to address all safety issues associated with the use of the
instrument and samples. It is your responsibility to establish health and safety practices and
determine the applicability of regulatory limitations.
•SBS only warrants the proper functioning of the SBS-3500 if no adjustments have been made to
the mechanics, electronics, and firmware.
•Only use the SBS-3500 for the purpose described in this instruction manual. SBS is not liable for
damages caused by incorrect use of the SBS-3500.
Installation and Use
•The SBS-3500 is not an explosion-proof instrument and therefore must not be operated in areas
with risk of explosion.
•Never remove the pump lock and battery cover in hazardous areas. Only exchange the batteries
outside of hazardous areas.
•The installation procedure shall only be carried out by authorized personnel who are familiar
with installation instructions.
•Do not use any accessories or wearing parts other than those supplied or approved by SBS.
•Make sure all operators are trained to use the instrument safely and correctly before starting
any applicable operations.
•In case of damage or malfunction, do not continue operating the SBS-3500. Do not operate the
instrument under conditions which could result in damage to goods and/or injuries and loss of
life.
•Check the SBS-3500 for chemical resistance to the samples and cleaning liquids.
•Do not expose the instrument to temperatures below 0ºC (32ºF) if water is contained in the
measuring cell or pump (freezing water will cause rupture of the measuring cell).
Maintenance and Service
•The results delivered by the SBS-3500 not only depend on the correct functioning of the
instrument, but also on various other factors. We therefore recommend you have the results
checked (e.g. plausibility tested) by skilled personnel before consequential actions are taken
based on the results.
•Service and repair procedures may only be carried out by authorized personnel or by SBS.

Page 8
•If your instruments need repair, contact your local SBS representative.
Disposal
•Concerning the disposal of the SBS-3500 observe the legal requirements in your country.
Precautions for Highly Flammable Samples and Cleaning Liquids
•Observe and adhere to your national safety regulations for handling the measured samples (e.g.
use of safety goggles, gloves, respiratory protection, etc.)
•Only store the minimum required amount of sample, cleaning liquids and other inflammable
materials near the SBS-3500.
•Do not leave sample/rinsing containers uncovered. Clean all spillages immediately.
•Make sure that the setup location is sufficiently ventilated. The environment of the SBS-3500
must be kept free of flammable gases and vapors.
•Supply a fire extinguisher.

3 Measuring Principle
Definition of Density
The density ρof a sample is defined as its mass divided by its volume:
Density is a temperature-dependant measuring unit.
The Oscillating U-Tube Principle
The sample is introduced into a U-shaped borosilicate glass tube that is being excited to vibrate at its
characteristic frequency electronically. The characteristic frequency changes depending on the density
of the sample. Through determination of the characteristic frequency the density of the sample can be
calculated. Due to the temperature dependency of the density value, the temperature of the sample
has to be determined precisely.
Concentration Measurement
In binary mixtures, the density of the mixture is a function of its composition. Thus, by using
density/concentration tables, the density value of a binary mixture can be used to calculate its
composition.
This is also possible with so-called quasi binary mixtures. These are mixtures containing two major
components and some additional ones which are present in very small concentrations compared to the
two main components. Many decarbonated soft drinks, for example, can be considered to be quasi
binary mixtures of sugar in water because the concentration of flavors and acids are very small
compared to sugar and water. Thus, the sugar concentration can be measured with a density meter.

4 SBS-3500 – An Overview
The portable density meter SBS-3500 measures the density of liquids in g/cm3 or kg/m3 according to the
oscillating U-tube principle. Apart from density you can select various further measuring units (relative
density, density at reference temperature, concentrations). A temperature senor measures the sample
temperature right at the measuring cell. The temperature is displayed and can be used internally for
automatic temperature compensation of the density reading if required.
Owing to the lightweight and compact design one can easily perform measurements of usually difficult
accessible samples. The backlight of the display ensures clear visibility of results, even in dark
surroundings. The backlight of the oscillator at the same time enables to observe the filling process in
detail.
Samples are filled into the measuring cell using the built-in pipette-style pump or a syringe. You can
allocate sample IDs to your samples for easier identification. You can also define and store different
measuring methods allowing acceleration of repeatedly performed standard measurements.
The SBS-3500 is operated via seven keys. 1024 measuring data including date, time and sample ID can
be stored in the memory of the SBS-3500 density meter and can be recalled, exported to a PC or printed
later. The transfer of the stored measuring data to a printer or PC is done wireless using an infrared
interface (IrDA).
The produce version SBS-3500 Tag&Log is additionally equipped with an RFID interface. Via this
interface data can be read in from an RFID tag and allocated to a sample ID and/or method. Later on, by
reading the RFID tag, you can switch fast and easily between different sample IDs and methods which
further increases the efficiency of your measuring process.

5 Checking the Supplied Parts
The SBS-3500 was tested and packed carefully before shipment. However, damage may occur during
transport.
1. Keep the packaging material (box, foam piece) for possible returns and further questions from
the transport company or insurance company.
2. Check the delivery for completion by comparing the supplied parts to those given in Table 5.1
3. If a part is missing, contact your SBS representative.
4. If a part is damaged, contact the transport company and your SBS representative.
