EM20I descrtption:
EM Series Portable toxic gas detection and alarm instrument (hereinafter referred to as the alarm), is a kind of continuous detection of toxic gas concentration, isintrinsically safe equipment to the explosion protectionrequirements. The detector is intrinsically safe typeproducts, in accordance with GB3836.1-2000 "explosivegas environment" guide to the operation of electrical equipment - part first: General requirements andGB3836.4-2000 "electrical equipment in explosive gasenvironment" in fourth parts: the relevant provisions ofthe intrinsically safe type "I".
The performance of EM detector is excellent, powerfulsound and light alarm, large screen display, easy to use,and is equipped with an intelligent sensor. All these features are concentrated in this small but strong gas detection instrument. EM series sensor for toxic gases,rapid response and accurate to ensure that there is any harm, can in time for your alarm. The EM series is the detection of gas in industry nowadays, the most sensitiveand can alarm. Application of a variety of environmentalis a challenge for gas detection instrument. In the hot,cold, wet, dirty or harsh environments. For example: in the oil platform or mine, use of the instrument is a kind of test. Design of EM series can be adapted to the extremeoperating environment. Explosion-proof fire retardantshell, strong light weight, easy to carry, can withstand theimpact. Whether it is accidentally fell on the ground or acollision, the EM series can monitor and alarm.
Product features:
1 small, explosion-proof housing strong, waterproofdesign.
2 screen LCD display, continuous real-time display gas concentration, need background light, press thebackground lamp special key.
3 with super sound, light, vibration and other 3 kinds ofalarm function.
4 using the rechargeable lithium battery, standby forabout a month or so.
The 5 alarm has low limit high limit, STEL, and TWA and other alarm function, and can according to customer needs to adjust the alarm value.
6 automatic zero and full-scale calibration function.
