Complete portable oxygen leak detector certificate Jiaxing, type approval certificate issued by the Ministry of Public Security and fire proof certificate, ISO-9000 certification, the oxygen concentration alarms are sold across the country, 10 years of production experience and high-end research team is the all walks manufacturers trustworthy, willing the majority of consumers come to purchase the oxygen concentration alarm. Fixed oxygen leak alarms [Installation Notes] Do not install directly affected by the neat, the fumes from the place. Do not install in the large air volume flow of the exhaust port, ventilation fans, door. Do not install in water vapor, water droplets place (90% relative humidity). Do not install place at a temperature below -30 ℃ and 90 ℃. . Do not press in the strong electromagnetic places. Stationary oxygen leak alarm Used line detector and controller quality control requirements: a field environment coated strong magnetic interference such as: high-power motor, high-voltage substations and other anti-jamming three core shielded cable should be used, no interference three core sheathed cable connection, the distance between detector and controller with 3 * 0.5 specifications can be less than 150 meters.
