Features Purpose: the gas meter is connected to a hose to measure the unidirectional airflow. Can be used to detect oxygen flow, control oxygen flow and detect gas flow Widely used: oxygen air flow meter can measure high furnace gas, coke gas, carbon gas, air, nitrogen, acetylene, phosgen, natural gas, liquid gas, hydrogen peroxide, flue gas, carbon dioxide, oxygen, compressed air, argon, toluene, ammonia and other gases 8mm Barbed - Oxygen Air Gas Conector is easy to use, with an 8mm barb for easy connection to the hose. The detectable range of the gas flow meter is 2.5 ~ 25 LPM Acrylic material: 2.5-25lpm flow meter is 100% brand new and made of high quality acrylic. It has a high degree of transparency and can clearly see the measured value. The flow meter can withstand pressures up to 0.6 MPa. 5% detection accuracy: the detection accuracy of the oxygen air gas capacitor is 5%, the pressure range is less than or equal to 0.6MPa (101.3KPa is recommended) and the temperature range is 0~60℃(20℃) recommended) Functions: This gas meter is connected to a hose to measure unidirectional gas flow. Made of high quality acrylic, it is transparent and can withstand a pressure of up to 0.6 MPa. It is easy to use and features 8mm barb for convenient connection to hoses. Can be used for high-oven gas, coking gas, air, nitrogen, acetylene, phosgen, hydrogen, natural gas, liquid gas, hydrogen peroxide, flue gas, methane, butane, chlorine gas, methane, carbon dioxide, oxygen, compressed air, argon, toluene, benzene, xylene, hydrogen sulphide, ammonia, etc. Mainly used to detect oxygen flow, control oxygen flow and can be used in industry.
