●High-precision temperature and humidity measurement (optional), while temperature compensation is performed on the sensor. The temperature range of the instrument is -40 to 70 degrees, and it can detect gas at 1300 degrees (optional high temperature sampling cooling filter handle or high temperature and high humidity pretreatment system)

●It can detect as low as 0.001PPM and as high as 99.999%Vol, and supports automatic switching between high and low ranges (please specify when ordering).

●Real-time detection or timing detection is possible (for the case where the amount of the gas to be measured is relatively small), the pump can be turned off when it is not detected to extend the startup time.

●It can be selected to detect 1 to 6 gases at the same time, up to 18, and the unit can be switched freely. The molecular weight of conventional gas does not need to be input, and the molecular weight of special gas needs to be automatically calculated and switched. Units are optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

●Three display modes can be switched: display the concentration of four gases at the same time, the concentration of a 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. Gas name, you can view the history curve graph.

●Chinese and English interface can be selected, the default Chinese interface, concise Chinese or English operation prompts, users of all ages can easily operate

●Data recovery function, selective recovery or full recovery, automatic identification and prevention of misoperation of concentration calibration, to avoid defects caused by human factors

●Zero point automatic tracking, multi-level calibration of target points, to ensure the linearity and accuracy of measurement, and can meet the national standards and the standards of local metrology bureaus at the same time.

●Can record calibration log, maintenance log, troubleshooting countermeasures, reminder of the expiration of sensor life, reminder of the next concentration calibration time
