Description
Product introduction:
This instrument is a portable multi-gas detector, which can continuously detect 4 kinds of gases at the same time: O2, LEL (combustible gas), CO, H2S. Each gas concentration reading is displayed on the LCD. The instrument allows users to set low-concentration/high-concentration alarm setting values, and STEL/TWA alarm function. When the detection result exceeds the preset alarm setting value, the instrument will alert the user with sound, light and vibration alarm.
