●Built-in pump suction measurement, integrated water vapor and dust filter, optional professional accessories for high temperature, high humidity, high dust environment, special road design, rapid response.

●2.31 inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, power, charging status and other information, and the menu interface adopts high-definition

The simulation icon shows the function name of each menu

●Large-capacity data storage function, standard 100,000 data storage capacity, larger capacity can be customized. Support real-time storage, timing storage, or only alarm concentration data

Check the time, support this machine to view and delete data, you can also upload the data to the computer through the USB interface, and use the upper computer software to analyze the data and store and print.

●USB charging port, can be charged by a computer or a power bank, compatible with phone chargers, overcharge, overdischarge, overvoltage, short circuit, overheat protection, 5-level precision power

Quantity display, support USB hot plug, the detector can work normally when charging, optional RS485 communication

●Using 4600mAH high-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.

●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), and temperature compensation for the sensor at the same time, the instrument uses a temperature range of -40 to 70 degrees, and can detect 400 degrees

Gas, higher temperature gas detection can be customized (optional high temperature sampling cooling filter handle or high temperature and high humidity pretreatment system)

●It can be selected to detect 1 to 4 kinds of gases at the same time, and the units can be switched freely. Normal gases do not need to enter molecular weight, and special gases need to enter molecular weight automatically.

Calculate and switch, the unit is optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

●Three display modes can be switched: display the concentration of four gas at the same time, the concentration of the single channel gas and the real-time curve are displayed in a large font cycle, between each channel

Automatic cycle or manual cycle can be switched, you can set whether to display the maximum value, minimum value, gas name, and view the historical record 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

●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.

●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.
