A Pressure Calibrator is an instrument used to generate, measure, and simulate precise pressure values to calibrate pressure gauges, transmitters, and switches. The main types include hand-held pneumatic or hydraulic calibrators (portable for field calibration) and bench-mounted dead weight testers (high-accuracy laboratory calibration). Pressure calibrators are widely used in industries such as oil & gas, chemical, power, and manufacturing to ensure the accuracy, reliability, and safety of pressure measurement instruments.
