Calibration Service

Pulsar Instruments offers traceable calibration for noise and vibration measurement equipment, with a five-working-day turnaround.

Pulsar Instruments offers traceable calibration for noise and vibration measurement equipment, with a five-working-day turnaround and optional UKAS calibration to ISO 17025:2017. Accurate noise meter and vibration meter calibration is essential – if you don’t recalibrate your equipment regularly, your measurements may not be seen as accurate, reliable or compliant.

What’s included?

Our calibration process typically checks more than 100 parameters to assess instrument performance. Fixed pricing includes firmware updates, performance adjustments, new batteries, minor repairs where required and a calibration certificate, with no hidden extras.

Annual servicing and calibration can also extend the warranty on eligible Pulsar instruments by a further 12 months, up to a total of 10 years.
