EM-4 4-in-1 Gas Detector

EM series gas detector own poweful sound and light alarm, super screen display, simple to use and equip the intelligentize sensor. It can measure various gas especially toxic gas and if some dangerous happened it will give an alarm, that’s why EM series can be the most senstive and alertable detector, because various environments is a challenge to gas detector like hot、cold、wet、dirty or harsh environment, for example of use in oil platform or in mines, the deisgn of this instrument can adapt to those extreme bad working environment, like ABS explosion-proof and fire-retardant housing、light-weight 、easy to carry and also withstand of the impact, whether accidental dropped to the ground or inadvertent collisions, it can still detect and alarm.

 

In the composite gas field,EM-4 is indeed a cost-effective detector

▲Antivibration housing Sturdy and Durable can be used in some bad environment

▲LCD continous display the timely gas thickness and corresponding element

▲NIMH rechargeable battery（ run 16-18 hours）

▲got 95db hearing alarm and two wide-angle visual alarm

▲Built-in vibration alarm adapt to high noise environment.

▲Backlight：when the light is dark / warning / when the users push any button

▲Four level alarm：lower limit and higher limit alarm adapt to whole gas,

▲Simple Auto Self-checking calibrating procedure and plug-in replaceable electrochemical sensor,

▲Record the element and thickness of gas in TWA、STEL and Peak Value, when in need it will display,

▲Full function and Auto testing：sensor、integrality of battery and circuit、sound and light vibration three level alarm.

▲small size，light weight（6X10X3.3 cm / 211g）
