* Waterproof, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, anti-static, anti-electromagnetic interference
* Protection level IP65, built-in water vapor and dust filter to prevent damage to sensors and instruments due to water vapor and dust
* Built-in pump suction measurement, quick response, sampling distance morethan 10 meters, special gas path design, direct detection.Negative pressure or positive pressure -0.5~2kg gas, no influence on the measurement result
* 4-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, power,Information such as charging status, the menu interface uses high-definition simulation icons to display the function names of each menu
* Large-capacity data storage function,100,000 data storage capacity, larger capacity can be customized. Support real-time storage, timing storage, or only alarm concentration data and time, support local viewing and deleting data,the data can also be uploaded to the computer through the USB interface, and the data can be analyzed, stored and printed with the host computer software.
* USB charging interface, can be charged by computer or power bank, compatible with mobile phone charger, overcharge,
overdischarge, overvoltage,short circuit, overheating protection, 5-level accurate power display, support USB hot plugging, the detector can work normally when charging, optional RS485 communication
* Using 4500mA large-capacity rechargeable polymer battery, which can work continuously for a long time
* Sound and light alarm, vibration alarm, visual alarm, under-voltage alarm, fault alarm, multi-directional three-dimensional display of alarm status when alarming.
* The alarm value can be set, and 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 -40-70 degrees,can detect 400 degrees 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 detect 1-4 kinds of gases at the same time, the unit is 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 the single channel gas and the real-time curve are displayed in a large font cycle, each channelcan be switched between automatic cycle or manual cycle. Can set whether to display the maximum value, the minimum value, and the gas name, and can view the history curve graph.
* Chinese and English interface can be selected, the default Chinese interface, concise Chinese or English operation prompts
* 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.
* Three-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 not detecting to extend the startup time.
* Can record calibration log, maintenance log, troubleshooting countermeasures, reminder of the expiration of sensor life, reminder of next concentration calibration time
