Calibration Gas Regulators
Demand Flow Regulators are used with devices that have a built in internal sample draw pump. Each DFR undergoes a 3 point leak check and gauge performance check. The flow is certified to NIST Reference materials and a Certificate of Assurance is supplied with every Regulator. Working Pressure is up to 3000 psig.
Examples:
- DFR 1-1 DFR with C-10 inlet, 3/16 Hose barb,1500 Psig Gauge
- DFR 1-1-1 DFR with C-10 Inlet, 3/16 Hose Barb and 3000 psig Gauge
Inlet | Outlet | Gauge (psig) | |||
---|---|---|---|---|---|
1 | C-10 | 1 | 3/16 Hose Barb | Std | 1500 |
1 | 3000 |
Fixed Flow Regulators provide a constant flow of calibration gas from the cylinder to the monitoring device. Available flows range from .2 LPM to 6 LPM. Each Absolute Accuracy regulator goes through a 3 point leak check process and the flow rate is certified to NIST traceable reference materials. A certificate of assurance is supplied with every regulator.
Examples:
- FF 0.5 is fixed flow regulator set at 0.5with a C-10 inlet, 3/16” Hose Barb outlet and 1500 Psig Gauge
- FF 0.2-1-1-A is Fixed Flow regulator set at 0.3 LPM with 1/4NPTF Inlet, 1/8” Hosebarb outlet and 3000 psig Gauge
