DryCal 1020 & 1500 DryCal

Tags: DryCal, 1020, 1500

Primary Flow Calibration Standard

For High Capacity Gas Flow

This powerful calibrator, featuring our patented proven DryCal® Technology is changing the game of flow calibration. The instrument has a range of from 5 to 1500 standard liters per minute (slpm) – more than ten times the volume of any other piston prover on the market! The portability of this model, which weighs in at 90lbs. is a dramatic and welcomed improvement over the cumbersome bell provers labs have used in the past.

For use with non-corrosive, non-condensing, non-combustible gases, less than 70% humidity.

Combine our DryCal primary piston provers with our new Integrator Pro to set up an analog MFC and MFM calibration station and power and control up to two voltage and two current mass flow devices at the same time.
