"Hidden risks in open flame, all accidents from the hidden, hidden is the source of the accident, and eliminate potential accidents is to prevent the first pass of the accident. The cause of the accident due to the presence of hidden numerous examples. The so-called "prevention is better than disaster relief, and that is to prevent accidents, prevention is the first one. Oxygen gas leak alarm device [Manager Tian 0531 -8 8790 109,1510 6,992,328] is a developed and produced in strict accordance with the national security industry standards designed to detect oxygen gas leak, 24-hour online monitoring alarm device. Oxygen gas leak alarm device Features: 1 with RBK-6000-2/RBK-6000-6-gas alarm controller supporting the use of; 2 using imported gas sensor, high precision and reliability; 3 three-wire structure; 4 compartment critical design applicable to the zone of dangerous conditions 1,2; 5 volume is small, easy to install; 6 Modular design for easy system maintenance; oxygen gas leak alarm instrument technical parameters: detection principle: Semiconductor / electrochemical / catalytic combustion type the import sensor detects gas: oxygen sampling methods: natural diffusion measurement accuracy: ± 5% FS response time: ≤ 30s working voltage: DC12V ~~ DC30V Temperature: -40 ℃ ~ 65 ℃ connection cable: ≥ RVV3 × 1.5mm2 transmission distance: ≤ 1200m explosion-proof grade: Exd Ⅱ CT6 installation ways: mounting bracket, steel pipes, wall mounted installation spiral: G1 / 2 "volume: 126mm (L) × 93mm (W) × 48mm (H) oxygen leak alarm device production through the development of high technology, meet the standard of the national security sector, after the majority of users to try and launch production, after the product into the market by the praise, the prospect of a vast oxygen leak alarm device has a sensor automatic identification and protection of over-concentration, short-circuit, open circuit and sensor and failure of the automatic detection function, good stability, high accuracy, anti-toxic, anti-interference ability and oxygen leaked Alarm to detect the concentration of a gas leakage in gas natural diffusion, with imported electrochemical sensor with excellent sensitivity and excellent repeatability; oxygen leak alarm device with embedded micro-controller technology, the Chinese menu is simple, full-featured, high reliability, and overall performance among the leading domestic level oxygen gas leak alarm instrument after-sales service: the product warranty for one year and lifetime maintenance. since the installation date for the user to create the file in order to better serve users Forewarned is forearmed, without prejudging the waste, security must firmly establish the principle of prevention is always a preventive measure, to far stronger after the accident to remedy the situation.
