★ The display unit can be switched freely.(no need to input molecular weight for conventional gas, input molecular weight of special gas, the detector will automatically calculate and switch).
Units optional: ppm, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.

★ Built-in pump suction, integrated water vapor and dust filter, fast response, support long distance sampling.

Built-in water vapor and dust filter to prevent damage to sensors and instruments, can be used in high humidity and high dust environments. The sampling distance is over 10 meters, and the special gas path design can directly detect; the negative or positive pressure of -0.5 to 2 Kg of gas has no effect on the measurement result.

★ Human-machine interface.
    2.5 inch high-definition color screen, display real-time concentration, alarm, time, temperature, humidity, storage, communication, power, charging status, concentration unit, gas molecular formula, gas name and other                  information the menu interface uses high-definition simulation graphics to display the function names of each menu.

★ Large-capacity data storage function, support multiple storage methods.
   Standard configuration of 100,000 data storage capacity, larger capacity can be customized; SD card storge is optional, support real-time storage, timing storage, or only alarm concentration data and time. Support local view       and  delete data, also can upload data to computer through USB, infrared communication and RS232, use upper computer software to analyze data, store and print.
   Remote wireless transmission is optional.

★ Multiple communication interfaces and printing functions
    USB, RS232 interface auto recognition, infrared interface is optional. External mini wireless infrared printer is optional.
    Print content: company name, gas name, date and time, ambient temperature and humidity, concentration data, test results (qualified).

★ High temperature gas detection.(optional)
    Optional high-temperature sampling cooling filter handle or high-temperature and high-humidity pretreatment system, can detect 1300℃ gas, higher temperature gas detection can be customized.

★ Three display modes can be switched.

    Simultaneous display of six gas concentrations, large font cycle display of single channel gas concentration, real-time curve. Automatic or manual cycle between channels are switchable. Can set whether to display the maximum value, minimum value, gas name, and view the historical curve graph.

★ Graphical display to reflect the trend of gas concentration change in a curve in a period of time.

★ Data recovery function

Partial or full recovery can be selected, eliminating worries caused by wrong operation.

★ Can set whether to display the maximum value, minimum value, average value.

★ USB charging interface, with charging protection function, support USB hot plug.
    Can be charged by computer or power bank, compatible with mobile phone charger; has overcharge, over discharge, overvoltage, short circuit, overheat protection; 5 levels of accurate power display.The detector works                normally when charging.

★ 6000mA large-capacity rechargeable polymer battery, it can work continuously for a long time.

★ High-precision temperature and humidity measurement (optional).

     It can do temperature compensate to the sensor at same time.

★ Support real-time detection or timing detection.

When not detecting, you can turn off the pump to extend the working time.

★ Various alarm modes, multi-dimensional indication of alarm status when alarm.
    Contains sound and light alarm, vibration alarm, visual alarm. Alarm types include: concentration alarm, under-voltage alarm, and fault alarm.

★ Alarm value can be set, multiple alarm mode settings.
    Low level alarm, high level alarm, interval alarm, weighted average alarm.

★ Mis-operation recognition function.

Mis-operation of concentration calibration can be automatically identified and prevented, which can avoid the defects caused by human factors.

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

★ Multi-level calibration of the target point to ensure the linearity and accuracy of the measurement.

★ Chinese and English interface for selection.

★ Logging.Record calibration log, maintenance log, troubleshooting measures, sensor life reminder, reminder for next concentration calibration.

★ Intrinsically safe circuit design.

Anti-static, anti-electromagnetic interference, passed the national standard test and CMC measuring instrument production license.

★ Protection grade up to IP67, water-proof, dust-proof, explosion-proof, shock-proof.
