Our warranty offers total confidence

Pulsar Instruments’ sound level meters, noise dosemeters and acoustic calibrators are well known for being robust and hard-wearing and come with a 1 year warranty. However, noise meter recalibration and service is an important factor of ensuring your equipment continues to function correctly; this is called in IEC standard 61672 for sound level meters or ‘Routine Verification’.

We recommend that your return your noise meter for service and recalibration on a yearly basis so you can have total confidence in your noise measurements. If you do, we will extend your warranty period for a further 12 months free of charge up to 7 years.

The Pulsar Warranty includes any faults on the sound level meter and accidental case damage. Please note the warranty does not cover accidental damage to the microphone or damage to the display.

After noise measurement recalibration of your instruments we issue you with a current and valid calibration certificate. We perform all calibrations in accordance with recommendations and  requirements of the appropriate International Standards and typically check over 100 different parameters.
