Desktop Hydraulic Piston Calibrator Dead Weight Tester Pressure Gauge Calibration Equipment
New Model Desk-top Hydraulic Piston Pressure Calibrator Dead Weight Tester Pressure Gauge Calibration Equipment
Description
New Model Luxury Desk-top Hydraulic Piston Pressure Calibrator Dead Weight Tester, Pressure Gauge is a Standard calibration. Dead weight testers are so called primary standards which means that the pressure measured by a dead weight tester is defined through other quantities; Length, mass and time. Typically dead weight testers are used in calibration laboratories to calibrate pressure transfer standards like electronic pressure measuring devices.
