T40-H2S(0-500PPM)
Gas Detector
The T40 Single Gas Detector is designed to protect the lives of people and detect the concentration of H2S or CO when exposed to dangerous gases in extreme environments.
Thanks to its rugged plastic housing and protective design, the T40 instrument can be used in climates such as deserts or the Arctic Circle. The instrument is small and lightweight, and can be easily clipped to a belt, shirt pocket or hard hat. The large LCD screen can clearly read out the gas concentration, type, peak and high-low concentration alarm levels. If the current high-low concentration values of the gas exceed the preset limit values, the instrument alerts the user with audible, visual and vibration alarms.
The peak hold function captures and records the maximum reading detected since the first power on. Calibration can be completed with a unique and simple flip lid operation (this design is patented in the United States).
The T40 is CHINA Coal Safety (MA) certified.
