●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, integrated water vapor and dust filter, optional professional accessories for high temperature, high humidity, high dust environment, rapid response; special road design, the sampling distance is greater than 10 meters.

●The 2.31-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, power, charging status and other information. The menu interface uses high-definition simulation icons to display the function names of each menu

●Large-capacity data storage function, support 100,000 data storage capacity, larger capacity can be customized. It supports real-time storage, timing storage, or only alarm concentration data and time, supports viewing and deleting data on this machine, and also uploads data to a computer through the USB interface, and analyzes the data with upper computer software and stores and prints.

●USB charging port, can be charged by computer or power bank, compatible with phone charger, overcharge, overdischarge, overvoltage, short circuit, overheat protection, 5-level accurate power display, support USB hot plug, the tester can be normal when charging Work, 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), while temperature compensation is performed on the sensor. The temperature range of the instrument is -40 to 70 degrees, and it can detect 400 degrees of gas. The detection of higher temperature gas can be customized (optional high temperature sampling and cooling (Filter handle or high temperature and high humidity pretreatment system)

●It can detect 1 to 4 kinds of gases at the same time, and the units can be switched freely. Normal gases do not need to input molecular weight. Special gases need to input molecular weight to automatically calculate and switch. 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 single-channel gas and the real-time curve can be displayed in a large font cycle, automatic or manual cycle between channels can be switched, whether to display the gas name can be set, and the history can be viewed Record the 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 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
