The PLUF series is a calibration bench for hammer union pressure gauges (and pressure sensors) independently developed by our company, designed primarily for the oil and gas industries. It offers users a choice between two sealing methods: a hammer union threaded connection and a one-touch automatic clamping seal. Once the gauge under test is securely clamped and sealed, the system performs the pressure calibration.
