Primary Pressure Standard
- Unique primary pressure and vacuum standard
- Pressure calibration range from 0.001 Pa to 40 kPa (FRS4)
- The FRS5 draws vacuum from 1 x 10-3 Pa.
- Vacuum calibration from 0-1 kPa upwards
- Used worldwide in national & accredited laboratories.
The Furness Rosenberg primary standards are of unique design and are used by national standards laboratories throughout the world. Based on a piston and balance principal they allow extremely high accuracy and control of ultra low pressure calibration.
