High Negative Pressure Gas Sampler Model FW-2

Eddie Technology High Negative Pressure Gas Sampler Model FW-2 Product Introduction
The FW-2 High Negative Pressure Gas Sampler is suitable for gas extraction pipeline systems and serves as a tool for collecting gas samples under negative pressure conditions. It is portable for fieldwork and easy to operate. The sampler consists of components such as an intake connector, exhaust connector, rubber plug valve, pull rod, piston, cylinder, and sealing rings.
Technical Parameters
Sampling Negative Pressure: 0–85 Kpa
Weight: 1.3 kg
Usage Method
Before collecting gas samples, connect the intake interface on the side of the sampler to the measurement nozzle at the inlet end of the orifice flowmeter. Connect the exhaust interface at the top to the gas detector.
During gas extraction, the rubber plug valve inside the side intake connector automatically opens, allowing high negative pressure gas to flow into the cylinder.
When injecting gas, quickly push the piston to open the core valve in the top exhaust connector. The rubber plug valve in the side intake connector automatically closes, allowing gas to flow into the high-concentration gas detector to measure the gas concentration.
