TD1198-H2S pumping hydrogen sulfide detector function to monitor the concentration of hydrogen sulfide in the environment or confined space and alarm with self-calibration function, zero calibration function, so that gas monitoring is more accurate, more reliable one key to restore the factory setting function, can be exempted To mishandle the trouble with temperature and pressure compensation, it can perfectly realize the compensation of gas concentration under different temperature and pressure environment. Two-stage sound and light alarm, the alarm point can set the large-capacity lithium polymer rechargeable battery pumping sampling method, the pump The suction adjustable shell adopts high-strength special engineering plastics, non-slip, waterproof, dustproof, explosion-proof exquisite high-grade aluminum alloy suitcase
