Feature:
Can continuous detection of toxic gas concentration, be applicable to the explosion place requirements of the intrinsically safe equipment. This detector for intrinsically safe products, in line with the GB3836.1-2000 "explosion operation guide gas environment electrical equipment" part 1: general requirements and GB3836.4-2000 "explosive gas environment electrical equipment" part 4: intrinsically safe "I" of the relevant provisions. EM electro detector excellent performance, powerful sound and light alarm, large screen display, the use of simple, and is equipped with intelligent sensor. All of these features all concentrated in this small and strong gas detector on. EM series of poisonous gas sensors to respond quickly and accurately to ensure that there is harm occurs, can in time for your alarm. EM series is the industrial field testing gas the most sensitive and can alarm detector. All kinds of application environment on the gas detector is a challenge. In the heat, cold, wet, dirty or bad environment. For example: in oil platform or mine, on the use of the instrument is a kind of test. EM series of design can adapt to these extreme bad working environment. Strong explosion flame retardant shell, light weight, easy to carry, also withstand impact. Whether accidentally fell down on the floor or centerless collision, EM series can still monitoring and alarm. |
Features, functions 1. Small, the strong explosion-proof enclosure, have waterproof model design. 2. Screen LCD liquid crystal display, can continuous real-time display gas concentration, need background light, can press the background light special key. 3. With super sound, light, vibration, three alarm function. 4. Use rechargeable lithium batteries, standby for about a month or so. 5. Alarm can have low limit, high limit, STEL and TWA and so on the many kinds of alarm function, and can according to the customer demand adjustment alarm value. 6. Automatic zero and full scale calibration functions. |
