1. Introduction to the SBS-2500
The SBS-2500 is a portable measuring instrument suited for determining the density of liquids. The instrument uses the oscillating body method.
To fill the measuring cell the built-in sample pump or a syringe may be used. The results are automatically calculated into one of the following
units: density, specific gravity, API degrees, Brix, % Alcohol, % H2SO4, Baumé, Plato, Proof or a user-defined unit. The value is then shown on the
backlit display.
For exact measurements, it is imperative to correct the temperature’s influence on the density. Depending on the selected unit the SBS-2500
carries out this result correction automatically. For this task, the instrument uses either internally-stored tables or one of the 10 temperature-
compensation coefficients entered by the user.
The results, along with the sample identification, temperature, temperature-coefficient, date and time can be saved. Together with the
instrument identification they can then, via the integrated infrared interface, be transferred to the computer or printed out on a printer.
2. Safety Measures
Measures for Your Protection and Operational Safety
Do not work in an explosion-hazardous environment! The instrument
housing is not gas tight. Otherwise, there is a risk of explosion from sparks
and/or risk of corrosion by gasses which can seep in.
•
Always hold the end of the sample tube over a waste container!
There is a risk of injury when emptying corrosive substances.
•
Leave the syringe in the sample intake after injecting a sample!
Otherwise, the sample will run out of the measuring cell.
1. Never press on the measuring cell window! This can influence the
oscillation characteristics of the measuring cell.
2. Do not clean the measuring cell with concentrated NaOH (caustic
soda) or HF (hydrogen fluoride)! Both substances chemically corrode
the measuring cell.
3. Use batteries of the specified type only. Otherwise, proper operation
cannot be guaranteed.
4. Do not submerge the housing in liquid! The instrument is only
resistant to splashed water.
5. Ensure that the following environmental conditions are met:
• no strong vibrations present
• not in direct sunlight
• no high humidity present
• no corrosive gasses present
• temperature between – 20 °C and 70 °C
•
no strong electrical or magnetic fields present
