Pressure Gauge Calibration

We use high accuracy Dead Weight Testers


Our pressure calibration services can be applied to a wide range of equipment from an analogue pressure gauge to the latest digital pressure device or fixed transmitter.

We use high accuracy Dead Weight Testers for the use of gauges used on liquid chemicals or other liquid forms. We have highly accurate Sika & Fluke digital pressure comparators which can only be used for clean air or nitrogen. All our calibration services are completely customisable to your exact requirements.

We offer a nationwide collection service for as little £8.89 each way per parcel.

Onsite Pressure Calibration Service

If sending your equipment out for calibration isn’t an option JBA Calibration Services can provide you with the perfect alternative with our cost-effective, friendly, and efficient onsite calibration service which is on hand 7 days a week, keeping production in the workplace moving.

Pressure and Vaccum Calibration: FAQs

1What instruments are used to calibrate a pressure gauge?
Common pressure calibration equipment used by calibration laboratories include dead weight testers and pressure calibrators. Traceable weights apply pressure on a fluid for the purpose of checking the pressure accuracy of different types of pressure gauge equipment.
2What are the signs of gauge failure?
Signs of gauge failure include overpressure, pressure spikes, mechanical vibration, pulsation and overheating. Gauges undergo calibration procedures every 12 months in order to receive a calibration certificate. However, these warning signs indicate your gauge needs immediate repair and calibration.
3How do you calibrate a pressure gauge?
To ensure your equipment is properly calibrated we record the following data:
  • The pressure of the reference instrument & indication parameters
  • Indication of the instrument under test
  • Values of influence qualities (temperature & atmospheric pressure)
  • Identification of the instruments included in the measuring system
