Product Introduction
This instrument is a portable multi-gas detector that can continuously detect 4 gases at the same time: 02, LEL (combustible gas), CO, HS. Each gas concentration reading is displayed on the LCD display. The instrument provides user-configurable low/high concentration alarms, as well as STEL/TWA alarm functions. When the test result exceeds the pre-set alarm setpoint, the instrument will alert the user with sound, light and vibration alarms.
