Product Overview
The PRX-DWT Series Piston Pressure Gauge Calibrator (Dead Weight Tester) is a high-accuracy primary pressure standard designed for precise pressure calibration applications. Pressure is generated by applying calibrated weights to a precision piston-cylinder assembly, providing stable, repeatable, and traceable pressure values.
This series is ideal for metrology laboratories, calibration laboratories, industrial facilities, and quality control departments where accurate reference pressure is essential.
Applications
- Calibration of precision pressure gauges
- Calibration of digital pressure gauges and meters
- Calibration of pressure transmitters
- Calibration of pressure sensors
- Reference pressure source for calibrating other pressure systems
- Laboratory and industrial metrology applications
