How 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. Sensors automatically correct for changes in air temperature and atmospheric pressure to provide accurate volumetric flow rate readings. Volumetric accuracy is 1% of reading and highly repeatable.
