This calibrator allows a technician to test the output or differential pressure (flow) readings
This calibrator allows a technician to test the output or differential pressure (flow) readings of a pneumatic instrument with one hand allowing the other hand to make calibration adjustments on the instrument being tested. The calibrator weighs only 8 oz. as compared to 3 or more lbs. for equipment marketed in kit form or one made up by the technician from parts.
The calibrator consists of sphygmomanometer-type (blood pressure) gauge accurate to 1% with a squeeze bulb for applying pressure manually and a precision-machined hand-adjusted valve to hold and relieve the calibrating pressure. A flexible hose and a 3/16" tube-1/4" NPT compression fitting is supplied for quick and easy connection to unit being tested.
