Pneumo Gauge Calibration

What is Pneumo Gauge Calibration?

Pneumo gauges are precision pressure gauges that are specifically designed for measuring depth below a reference surface. These specialised depth gauges are used extensively in onshore and offshore commercial diving operations, as well as in submarines and other submersibles, to monitor diver depth. Pneumo gauges are also used to measure the pressure within hyperbaric chambers, which are typically used to treat decompression sickness.

When working in underwater and subsea environments, every last detail needs to be planned, monitored and logged. The lives and livelihoods of divers and dive teams depend on the accuracy of their equipment. This is why regular pneumo gauge calibrations are essential. A professional depth gauge calibration can ensure that your depth gauges continue to perform with their specifications, maintaining the safety of all your dive personnel.

How to calibrate a Pneumo Gauge

A pneumo gauge calibration involves taking readings from a depth gauge and comparing those with known specifications. If the readings deviate from those specifications, then the depth gauge requires adjustment. Our GNW technicians can carry out a fully traceable pneumo gauge calibration either off-site at our specialised facilities in Southport, Merseyside or on-site at your premises on a scheduled date, depending on your specific needs.

If time is of the essence, and you would like to maintain full visibility of your instrumentation, GNW can undertake an on-site pneumo gauge calibration of your depth gauges. An on-site depth gauge calibration delivers same-day results and eliminates any interruptions to your operations. Otherwise, we can perform certified off-site pneumo gauge calibrations to within an accuracy of ±0.25% with an average turnaround of just a few days.
