Overview

Chek-Mate Air Sampling Pump Calibrator Overview

The proof is in the performance with the SKC Chek-Mate Air Sampling Pump Calibrator! With a volumetric accuracy of 1%, the SKC Chek-Mate is the smart choice for air sample pump calibration. Simple to use with a one button operation, the SKC Chek-Mate Air Sampling Pump Calibrator meets the accuracy requirements of MDHS 14/4.

How the SKC Chek-Mate Works

The SKC Chek-Mate Calibrator is a highly reliable orifice-type airflow meter that incorporates sensors to measure pressure drop across a fixed orifice. The sensors automatically correct for changes in air temperature and atmospheric pressure to provide accurate volumetric flow rate readings.
