●It can be selected to detect 1～4 kinds of gases at the same time, and the unit can be switched freely. Units are optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb


●Three display modes can be switched: display the concentration of four gases at the same time, the concentration of single-channel gas and the real-time curve can be displayed in a large font cycle, and the automatic cycle or manual cycle between the channels can be switched. You can set whether to display the MAX value, MIN value, Gas name, history can be viewed.


●Chinese and English interface can be selected, the default Chinese interface


●Data recovery function


●Zero automatic tracking


●Multi-level calibration


●Mistaken operation of concentration calibration is automatically identified and prevented


●Support OEM or ODM customization, RS485 communication is optional


●Optional environmental temperature and humidity measurement function, more other functions or communication interface can be customized.
