Description
Taylor Environmental Sciences model 44S390 squueze bulb pressure calibrator 0-18 PSI dial gauge with a bulb and manually operated valve for the use as an alternate to a manometer in calibrating pressure instruments. The dial is marked for 0 to 18 Psig and is accurate within 1% of range span.
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 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.
