  • ★It is possible to simultaneously detect 1 ~ 4 types of gases, and the units can be switched freely . Units that can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/l.
  • ★Built-in pump-suction type measurement, built-in water vapor, dust filter, so as to prevent the damage of sensors and instruments due to the water vapor and dust.
  • ★Rich human-machine interface
    2.31-inch high-definition color screen, display the information such as real-time concentration, alarm, time, temperature, humidity, storage, and so on.

  • ★Function of large-capacity data storage (capacity can be customized), multiple storage modes are supported, and RS485 communication is an optional configuration.
  • ★High temperature gas detection (optional)
    The optional high-temperature sampling and cooling filter handle or high-temperature high-humidity pretreatment system will be possible to detect the smoke gas at the temperature of 400 ℃. The detection for the gases at higher temperatures can be customized.

  • ★It is possible to switch among three display modes .
  • ★Graphical display, and use the form of curve to reflect the trend of gas concentration changes in a certain period of time.
