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

● High precision temperature and humidity measurement (optional), and temperature compensation for the sensor, the instrument uses a temperature range of -40 ~ 70 degrees, can detect 400 degrees of gas, higher temperature gas detection can be customized (optional high temperature sampling and cooling filter handle or high temperature and high humidity pretreatment system)

● Can be selected to detect 1 ~ 4 kinds of gas at the same time, the unit is free to switch, conventional gas does not need to input molecular weight, special gas needs to input molecular weight automatically calculated and switched, the unit is optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

● Three display modes can be switched: display four gas concentrations at the same time, large font circulation display single-channel gas concentration, real-time curve, automatic cycle or manual cycle between channels can be switched, you can set whether to display the maximum value, minimum value, gas name, you can view the historical record curve.

● English and Chinese interface can be selected, the default Chinese interface, simple Chinese or English operation prompts

● Data recovery function, can be selective recovery or full recovery, eliminating the worry caused by misoperation

● Zero automatic tracking, long-term use is not affected by zero drift.

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

● The concentration calibration error operation is automatically identified and prevented, which can avoid the bad caused by human factors.

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

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