Pressure gauge calibration and pressure instrument calibration
From utility lines to cleanroom pressure cascades, pressure readings drive safety and quality decisions. We calibrate gauges, transmitters and switches against traceable pressure standards and document every test point.
Gauges, transmitters and switches you can trust
Pressure instruments sit on compressors, boilers, autoclaves, process lines, gas manifolds and cleanroom walls. A gauge that sticks, a transmitter that drifts or a switch that trips late can affect product quality, equipment protection and personal safety.
We calibrate analogue and digital pressure gauges, vacuum gauges, differential pressure gauges used in cleanrooms, pressure transmitters, pressure switches, indicators and controllers. Each instrument is checked at several points, rising and falling, so hysteresis and repeatability are visible as well as accuracy.
Where an instrument feeds a control loop, we record as-found and as-left results so your maintenance team can see exactly what changed.
Pressure errors cost more than calibration
Process quality
Pressure drives flow, temperature and reaction conditions. Accurate gauges keep batches consistent.
Equipment protection
Switches and safety settings only protect equipment if they act at the right pressure.
Cleanroom compliance
Differential pressure gauges prove your cleanroom pressure cascade. Read our differential pressure testing guide.

Where pressure calibration is needed
How the work is carried out
Instrument review
We note range, accuracy class and application for each instrument.
Multi-point check
Readings are compared with a traceable standard at several points up and down the range.
As-found and as-left
Results before and after any adjustment are recorded where applicable.
Certificate
A certificate with results, uncertainty and status is issued per instrument.
