What is a Dead Weight Tester?
A dead weight tester is an instrument that calibrates pressure by determining the weight of force divided by the area
Calibration
Instrumentation Calibration helps us to maintain and verify sensor accuracy. Different field instruments typically Flow, Pressure, Temperature, Level, etc.
