Particle Counter Calibration

Particles Plus Calibration UK

The calibration of particle counters and other monitoring equipment gives verified assurance that units are operating within acceptable tolerances. A calibrated unit can be trusted to perform accurately and reliably.

How often should I calibrate my particle counter?

21501-4:2018 states, "The calibration of the LSAPC should be conducted at an interval equal to or shorter than one year. The requirements should be met during the calibration interval".

The calibration certificates we provide cover your unit for 12 months.
