Deadweight Testers

Deadweight tester calibrators are primary pressure standards used to generate highly accurate, traceable pressure by applying calibrated weights to a precision piston‑cylinder assembly. They are essential for high‑accuracy pressure calibration, making them a cornerstone of calibration laboratories, metrology programs, and compliance‑driven industries. Key applications include calibrating pressure gauges, transmitters, sensors, and validating other pressure calibrators across low‑ to very high‑pressure ranges.
