SK-2300 High Pressure Hand Pump Calibrator measures pressure up to 600 Kg/cm2 whose principle of operation based on the movement of calibrate handle operated manually which moves the piston back and forth leading to the formation of suction and deliver water or oil used for pressure generation. A Calibration Pump is a manual or pneumatic device used to generate precise pressure levels for testing and Calibrating Pressure-Measuring Instruments like gauges, sensors, and transmitters. Applications: Used for calibration purpose and testing for Vacuum and pressure gauges in laboratories, filter monitoring, room pressure monitoring, On field Calibration, Calibration Lab, Validation Lab.
