Introduction
The SBS 2500 is a portable measuring instrument suited for determining the
specific gravity 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 specific gravity, the value is then
shown on the backlit display.
The results, along with the sample identification, temperature, temperature-coef-
ficient, 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.

Safety measures
Measures for your protection
- Do not work in an explosion-hazardous environment! The instru-
ment housing is not gastight. 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.
Measures for operational safety
- Never press on the measuring cell window! This can influence the
oscillation characteristics of the measuring cell.
- Do not clean the measuring cell with concentrated NaOH (caustic
soda) or HF (hydrogen fluoride)! Both substances chemically cor-
rode the measuring cell.
- Use batteries of the specified type only. Otherwise, proper operation
cannot be guaranteed.
- Do not submerge the housing in liquid! The instrument is only
resistant to splashed water.
- 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
