Diesel alarm with the recognition sensor failure and provides a high concentration of gas overrun protection. [Lyla (0531-58669819 15269173085) For details, please call us】 When the sensor due to aging may lose function, the detector can automatically identify and police, effectively avoid false negatives. Diesel alarm advance warning of diesel gas concentration, to avoid poisoning and casualties. Diesel alarm can be divided into open, the controller put in gas easily leak detectors can be placed not too far away from their office or duty room, which is more convenient to view the gas concentration at any time, improve the safety factor of industrial production. The use of imported diesel alarm sensor as a detection device, the fast and accurate detection rate. Diesel alarm detected the environment concentration levels reach preset alarm value, the diesel alarm immediately sound and light alarm, to remind us to take security measures in a timely manner, at the same time will drive the sprinkler system to cut off the air flow to prevent poisoning, Item corrosion accident. Portable gas detector technical parameters: sampling methods: diffusion detection range: 0-100% LEL accuracy: ± 5% (FS) Alarm volume: ≥ 80dB response time: ≤ 30s recovery time: ≤ 60s proof grade: Exd Ⅱ CT3 alarm points: -reporting of 25% LEL high reported 50% LEL Power Supply: 4.8V 1300mAhr NI-MH rechargeable battery indicator mode: 3 LED digital display with status indication of the use of the environment: temperature -40 ℃ ~ 70 ℃ Humidity <90% RH no condensation Dimensions: 120mm * 38mm * 68mm portable gas detector main characteristics: high-speed CPU processor, fast and accurate processing system tasks, to ensure the reliability of the detector using imported gas sensors, high precision, reliability response and recovery time, good gas selectivity, anti-interference ability LCD display, can be displayed in real time gas concentration, LCD organic light-emitting screen, shock resistance, good volume, light weight, low power consumption, easy to carry using high-performance lithium battery, long working hours, while charging protection and low voltage protection, ensure that the battery is more reliable, longer life fast warm-up, the response time of rapid extension tube design, no dead ends handheld diesel leak detector gas detector, in accordance with GB15322.1-2003 "combustible gas detector standard strict design and manufacturing, and through the inspection of the Fire product quality supervision departments. Handheld diesel leak detector is a single-chip micro-computer controller do signal processing institutions, gas detection element is the use of imported special sensor with high sensitivity, stable, long life, low power consumption advantages. Gas detector portable the xylene gas detection instrument RBBJ-T large-screen LCD display for easy viewing, compact, lightweight and can easily clip on pocket, belt or helmet.
