Suzhou portable oxygen 02 concentration Alarm 【Lyla (0531-58669819 15269173085) For details, please call my company] is a continuous detection of gas concentrations in the operating environment intrinsically safe instrument. Suzhou portable oxygen 02 concentration Alarm apply to gas leakage rescue, underground pipelines, mines and other places, can effectively guarantee the safety of the staff of life are not infringed, without loss of production equipment. Suzhou portable oxygen 02 concentration Alarm natural diffusion detect gas concentration, using imported electrochemical sensor with excellent sensitivity and excellent repeatability; instrument uses embedded micro-control technology, Chinese menu, simple operation, full-featured. Concentration of oxygen leak detector 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 point : Low reported 25% LEL high reported 50% LEL Power: NI-MH 4.8V 1300mAhr 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 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 fast. gas selectivity and anti-interference ability LCD display, real-time display of gas concentration, LCD organic light-emitting screen, shock resistance good small size, light weight, low power consumption, easy to carry high-performance lithium battery, long working hours, charge protection and low voltage protection at the same time, ensure that the battery is more reliable and longer life fast preheat, the response time of rapid extension tube design, no dead ends oxygen leakage alarm gas detector, oxygen leak alarms, alarm oxygen concentration; oxygen leak detector; the oxygen alarm host; oxygen probe; oxygen leak detector; oxygen leak detector; oxygen alarm; oxygen detector; oxygen monitor alarm devices; oxygen leak detector, the oxygen leak detection instrument, paint leak detector, oxygen detectors, oxygen gas detectors, oxygen leak detection alarm. The company has a comprehensive after-sales service team, effective and innovative technical team.
