How Demand Flow Works
🔵
Calibration Gas Cylinder
CGA 600 connection screws onto standard cal gas cylinder
→
⚙️
Demand Flow Regulator
Delivers only what the instrument pump pulls — no wasted gas, no flow meter needed
→
📟
Gas Detector
PS200 / PS500 or other pumped detector — self-regulates intake via internal pump
No sample bags, no flow meters, no special training required. The demand flow design automatically matches gas delivery to the instrument's pump demand — preventing over-pressurization and wasted calibration gas.
Instrument Compatibility
- GMI PS200 4-Gas Detector (primary application)
- GMI PS500 Series Gas Detectors
- Any pumped (aspirated) gas detector requiring demand flow calibration with CGA 600 gas cylinders
Important Notice
Not suitable for reactive gases. This demand flow regulator is NOT designed for use with highly reactive calibration gas mixtures such as chlorine (Cl₂), hydrogen chloride (HCl), ammonia (NH₃), or similar corrosive compounds. For standard LEL/O₂/CO/H₂S calibration gas mixtures only.
