Producer of the FRS4 referenc pressure standard for calibrations of pressures from 0-40kPa:
- a non-rotating piston gauge
- with automatic control system
- Proven performance
- ease of use
Providing long-term stability of calibration for laboratories around the world, the FRS4 is a piston gauge pressure calibrator for use in gauge and differential pressure modes.
The precision manufactured piston assembly produces a differential pressure that is directly related to physical properties.
Highly stable, the instrument gives you confidence in the long-term traceability of your calibrations.
The FRS4 has proven its reliability in national and
accredited laboratories for over 20 years.
Supplied in four different versions, the FRS4 covers a range from zero to 40kPa for the highest-pressure version, and zero to 3.3kPa for the lowest. The lowest-pressure model can provide a resolution down to 0.001Pa, all with an uncertainty of 0.005% of reading (+0.002Pa).
