Premium Flow Meter: The gas flow meter is made of high quality acrylic. Transparent appearance. With good performance, the flow meter can withstand pressure up to 0.6MPa How to Measure: This gas gauge is connected to a hose to measure one-way gas flow. The meter is therefore mainly used for detecting oxygen flow and controlling oxygen flow and can be used in industry Versatility: Gas flow can measure furnace gas, cosofene gas, charcoal, air, nitrogen, acetylene, phosgues, hydrogen, liquefied gas, hydrogen peroxide, methane, butane, chlorine gas, carbon dioxide, oxygen, argon, toluene, benzene, xylene, sulfur sulfide, ammonia. etc Easy to use: This LZQ-7 gas flow meter is easy to use. The flowmeter is equipped with an 8 mm resistance hook for easy connection to pipes, which reduces labor resistance, speeds up construction and reduces construction costs Note: Due to the different monitor settings, the items color may be slightly different from the pictures. Measurements are taken by hand, the sizes indicated may vary by 1-3 mm This gas meter is connected to a pipe to measure one-way gas flow. Made of high quality acrylic, it is transparent and can withstand up to 0.6MPa. It is easy to use and has an 8mm carabiner for convenient connection to pipes. Can measure high furnace gas, cosofen gas, coal gas, air, nitrogen, acetylene, phosgue, natural gas, hydrogen peroxide, smoke gas, methane, butane, chlorine, methane, carbon dioxide, oxygen. Compressed air, argon, toluene, benzene, xylene, sulfur hydrogen, sulfur dioxide, ammonia, etc. Mainly used to capture oxygen flow, control oxygen flow, and can be used in industry.
