The preferred implementation concrete according to another kind of the present utility model, described attention device are alarm lamp and/or hummer and/or vibrating device.According to attention device type difference, bright lamp, buzzing or vibration alarm prompting appear recording when the harmful gas concentration data are higher than designated value.
Preferably, the outside of the gas receiving end of described sensor is provided with wire gauze, can wrap up the sensor outer end, is used to intercept that dust, willow catkins flying in the air etc. may influence, the exotic of obstruction sensor.
More preferably, the gas receiving end outside of described sensor also is provided with sender unit cap, is connected with shell by screw thread, plays a protective role when detector is idle.
The preferred implementation concrete according to another kind of the present utility model, there is clamping device at the described shell back side, can be fixed on detector on clothes, the belt.
More preferably, the seam between described shell and control panel, screen, the button is provided with waterproof vibration isolation circle.
[beneficial effect]
The harmful gas detector that the utility model provides is simple in structure, and volume is little in light weight, can carry all kinds of operation fields.This equipment can detect the concentration of multiple inflammable gas, comprises sulfuretted hydrogen, carbon monoxide, hydrogen, can also detect oxygen concentration, and different operation fields is had good adaptability.
