Demand Flow Regulator DFR for Calibration Gas Cylinders
Demand Flow Regulator (DFR) Used for the calibration of gas monitors / detectors
Supplies gas as demanded by an gas monitor or analyzer and automatically shuts off. This highly sensitive single stage DFR allows for reduced testing time, permitting the flow of gas at less than one inch water column.
- Made from Clear Anodized 6061-T1 aluminum
- Fits Calibration Gas Cylinders with C10 Fitting (34, 44, 58, 66, 74, 100, 105, 116 Liter Aluminum and 103 Steel Cylinders)
- Nickel plated brass
- 0-1200 PSI gauge
- 3/16" hose barb
- Viton O-rings and diaphragm
- Made in the USA
Demand flow regulator (DFR) is designed for use with instruments that utilize a sample draw pump to draw the calibration gas. This regulator provides the exact amount of gas that the instrument pump requires. This type of regulator makes calibration quick and easy by eliminating the need for sample bags, flow meters, or special operator training. In addition, it saves calibration gas because it only transfers as much gas as the instrument demands.
Typically used for Gas Monitoring Docking Stations. For use with cylinders with C10 fitting.
Also known as a pressure reducing regulator, vacuum actuated regulator, or sample regulator.
Compatible for use with- REG-DF-1, N600 1001 33, 18102509, 51700, 1419-216, 2004, and 75-DFR
