| 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. The calibrator consists of sphygmomanometer-type (blood
pressure) gauge accurate to 1% with a squeeze bulb for applying
pressure manually and a precision-matched 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 the unit being tested. |
