Pressure Gauge Calibration
GNW is a reliable, trusted and experienced service provider for pressure gauge calibration. Learn more about how we can help below, or get in touch straight away by filling out or form or visiting our contact page.
Regular pressure and vacuum gauge calibration give you absolute confidence that your instruments are reading correctly. This enables you to avoid any costly production mistakes and delays, whilst ensuring the safety of your site. At GNW, we have more than 40 years of experience in pressure and vacuum gauge calibration. Our technical team is able to calibrate and certify any vacuum and pressure gauge using our accurate, traceable test equipment.
We have an array of pressure and vacuum gauge calibration equipment to perform hydraulic, pneumatic and oil-free calibration procedures to suit both your gauges and your application. Our traceable test certificates show rising and falling pressure readings, as well as any errors found during the calibration. Our technicians can also perform minor adjustments where possible to bring your pressure and vacuum gauges back to specification.
Types of Pressure Guage Calibration
There are three main types of pressure that are typically measured across industries. Absolute Pressure is the pressure relative to a complete vacuum. Gauge Pressure is the difference between an absolute pressure and the prevailing atmospheric pressure. Differential Pressure is the difference between any two applied pressures. Most pressure readings fall under the broader category of differential pressure, including absolute and gauge pressure.
A wide range of pressure devices that measure these types of pressure can be calibrated, including:

On-site Pressure Gauge Calibration
Our fully mobile GNW technicians will carry out an on-site pressure and vacuum gauge calibration of your instruments at a time and date that is convenient for you. We can calibrate a wide range of instruments from all the major calibrated pressure gauge suppliers. This service is ideal for companies with a large inventory of gauges or bulkier items that cannot be shipped, as well as those involved in time or process-sensitive operations.
In-house Pressure Guage Calibration
GNW can undertake the calibration of vacuum gauges from 0 to -1 bar (-30 inHg) and can perform minor adjustments at our headquarters in Southport. We can also calibrate a wide range of pressure gauge types, from simple handheld digital manometers to complex digital pressure gauges. This service is ideal for customers who require a rapid calibration (often just a couple of days) but don’t require the immediacy of on-site calibration.

Frequently asked questions
If you can’t find what you’re looking for simply get in touch with our friendly team who are here to answer any questions you might have.
Pressure gauge calibration compares readings from a measuring instrument with known specifications. If the readings deviate from those specifications, then the pressure gauge requires adjustment. Pressure gauge readings are essential to many production processes, which means pressure gauge calibration should be a priority.
