Chek-mate Calibrator
chek-mate Calibrator, with NIST Certification.
The SKC chek-mate Calibrators are highly accurate and reliable differential pressure airflow meters that incorporate 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 without the inconveniences of piston-style calibrators.
Medium Flow and High Flow chek-mate Calibrators feature CalChek automatic calibration for CalChek-ready AirChek® TOUCH and Leland Legacy® sample pumps. Used with the CalChek Communication Cable and pulsation dampener, calibration becomes as simple as building the calibration train, setting pump flow, and letting CalChek take over.
- Range 5 mL/min to 5 L/min
- Average flow display feature
- Built-in sensors adjust for changes in temperature and
atmospheric pressure - User-selectable Flow Units and Time Intervals
- Sleek design for calibration anywhere, anytime
