Accurate Calibration Services for Instruments, Test Meters & Gauges

With calibration prices starting from as low as £25, PASS Ltd provides an affordable, fast and professional way to ensure your test equipment and tools are calibrated to traceable standards.

Our UKAS-accredited* calibration laboratory is able to facilitate the calibration of a wide variety of testers ranging from electrical meters, such as multimeters and clamp meters, to specific testers such as barometers, vacuum gauges, anemometers, digital thermometers and much more. We also calibrate several tools including torque screwdrivers and wrenches, steel rules, theodolites and vernier calipers.

For many testers, we offer a 3-day-turnaround service as standard, where we will dispatch your tester, fully calibrated, from our lab within 3 working days of receipt!
