The T40 single gas detector is designed to protect the safety of personnel and detect the concentration of dangerous gases H2S or CO when exposed to extreme environments. The instrument can be used in variable and abnormal climate environments such as deserts or the Arctic Circle.
The instrument is small and lightweight and can be easily clipped to a belt, shirt pocket or helmet. The large LCD screen can clearly read the gas concentration, type, peak value and high and low concentration alarm levels. .If the current high and low gas concentration values ??exceed the preset limits, the instrument will alert the user with sound, light and vibration alarms.
The Peak Hold function captures and records the maximum reading measured since first power-on. Calibration can be completed with a unique and simple flip-up operation. This design has been patented in the United States.
