Primary Flow Calibration Standard
For High Capacity Gas Flow
Featuring Proven DryCal® Technology, the DryCal 1020 and 1500 provide high-capacity primary gas flow calibration from 5 to 1500 standard liters per minute (slpm). The compact piston-prover system provides a practical alternative to traditional large bell provers for laboratory and calibration applications.
DryCal Technology provides accurate and reliable gas flow readings independent of the gas species measured. For use with non-corrosive, non-condensing, non-combustible gases at less than 70% humidity.
