The patented two stage DFR 2000 series regulator is designed
for use with instruments that utilize a pump to draw the
calibration gas. The regulator provides the exact amount of gas
the instrument pump requires. This simple-to-use regulator
makes calibration quick and easy by eliminating the need for
sample bags, flow meters, or special operator training.
