CMR Controls CAL95 Micro Manometer Calibrator Description

The CMR Controls CAL95 Micro Manometer Calibrator is designed to calibrate pressure or velocity transmitters. The unit is ideal for situations where accuracy and a fast response is necessary, such as differential pressure measurement, as well as long-term monitoring. It is also ideal for commissioning work due to its compact yet powerful design. This pneumatic calibrator is available for rent from as little as £90 per week.
