●Alarm value can be set, the alarm mode can be low alarm, high alarm, interval alarm, weighted average alarm

●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 gases at 800 degrees. The detection of higher temperature gases can be customized (optional high temperature sampling and cooling (Filter handle or high temperature and high humidity pretreatment system)

●It can detect 1~5 kinds of gases at the same time, and the units can be switched freely. Normal gases do not need to enter the molecular weight, and special gases need to enter the molecular weight to automatically calculate and switch. The 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, you can recover selectively or fully, eliminating the worries caused by misoperation

●Zero point automatic tracking, long-term use will not be affected by zero point drift.

●Multi-level calibration of the target point to ensure the linearity and accuracy of the measurement, and it can meet the national standards and the standards of the local metrology bureau at the same time.

●Mistaken operation of concentration calibration is automatically identified and prevented, which can avoid defects caused by human factors.

●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.

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