Product Information

A four-gas alarm detector designed to protect the user's safety in a dangerous work environment where an explosion may occur.The instrument can simultaneously display four concentrations of gas (oxygen, carbon monoxide, hydrogen sulfide and gas) on a digital liquid crystal display, and the method of operation and calibration is very easy and convenient. Four different gases are detected simultaneously. The explosion-proof structure is safer. Rubber material housing can provide shock protection. With external sampling pump and probe. Automatically light the alarm. Rechargeable batteries are compatible with alkaline batteries. Excellent waterproof/dustproof structure. High performance sound, vision, vibration alarm. High alarm, low alarm, STEL and TWA can be set alarm. Scope of application: It is used to detect the concentration of toxic gases in oil, chemical, pharmaceutical and other fields in real time.
