This gas meter is designed to be connected to a hose to measure unidirectional gas flow. It provides a simple, quick way to verify gas movement in a line. Key features - Material and visibility: Made of transparent acrylic for clear view of flow status; rated to withstand up to 0.6 MPa. - Easy to install: Simple to use with 8 mm barbs for convenient hose connections. - Wide gas compatibility: Can measure furnace gas, oven gas, coal gas, air, nitrogen, acetylene, phosgene, hydrogen, gas, liquefied gas, flue gas, methane, butane, gas, methane, carbon dioxide, oxygen, compressed air, argon. Benefits - Enables rapid, at-a-glance checks of gas flow in one direction. - Transparent body helps you inspect the meter and connection points without disassembly. - Robust enough for common heating, welding, and laboratory environments, while remaining lightweight and simple to use. Use scenarios - In home or commercial furnaces and ovens during servicing to confirm fuel gas flow and connections. - In welding, lab, or workshop settings to connect to nitrogen, argon, acetylene, hydrogen, or other listed gases for quick checks. - In flue or exhaust lines to monitor the presence and movement of gases such as methane, carbon dioxide, or other specified gases.
