Multi-parameter Detect Alarm, detector, oxygen, CO

Multi-parameter Detecting Alarmis a new generation of intelligent multi-parameter detector which adopts low power consumption design. It has the characters of sound & light alarm, a detector serves several purposes, small and light. It can be widely used for continuously measuring multi-parameters of the gases existing in special environment such as methane, oxygen, carbon monoxide, sulfured hydrogen, temperature, and humidity.
