"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. Hydrogen sulfide 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 hydrogen sulfide gas leak, the 24-hour online monitoring alarm device. Hydrogen sulfide gas leak Alarm Features: 1 with RBK-6000-2/RBK-6000-6-gas alarm controller supporting the use; 2 import gas sensor, high precision, high reliability; 3 three-wire structure; 4 proof design suitable for the dangerous conditions 1,2 district; 5 small size, easy to install; 6 Modular design for easy maintenance; technical parameters: hydrogen sulfide gas leak alarm device detection principle: semiconductor / electrochemical / catalytic combustion imports sensors detect gases: hydrogen sulfide sampling methods: natural diffusion-type measurement accuracy: ± 5% FS response time: ≤ 30s working voltage: DC12V ~~ DC30V Temperature: -40 ℃ ~ 65 ℃ connection cable: ≥ RVV3 × 1.5mm2 transmission distance: ≤ 1200m proof grade: Exd Ⅱ CT6 installation: mounting bracket, steel pipes, wall mounted installation spiral: G1 / 2 "volume: 126mm (L) × 93mm (W) × 48mm (H) hydrogen sulfide leak alarm instrument through high-tech technology R & D and production, in line with national standards for the security sector, after the majority of users to try and launch production into the market by the praise, the prospect of a vast hydrogen sulfide leak alarm device has a sensor over-concentration, short-circuit, open circuit automatic identification, protection and sensor and failure of the automatic detection function, good stability, high accuracy, anti-toxic, anti-interference ability. hydrogen sulfide leak alarm device to detect leaking gas concentration gas natural diffusion, equipped with imported electrochemical sensor with excellent sensitivity and excellent repeatability; hydrogen sulfide leak alarm device embedded micro-controller technology, the Chinese menu is simple, full-featured, high reliability, and overall performance among the leading domestic level. meter of hydrogen sulfide gas leak alarm after-sales service : The product warranty for one year, lifetime maintenance. since the installation date, the company for the user to create the file, in order to better serve users Forewarned is forearmed, without prejudging the waste safety work must firmly establish prevention as the principle of the Lord, always a preventive measure, is much stronger than the accident to remedy the situation.
