★ It can detect 1 to 4 kinds of gases at the same time, and the unit can be switched freely. Units are optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.

★ Built-in pumping measurement, integrated water vapor and dust filter to prevent damage to sensors and instruments due to moisture and dust. It can be used for high humidity and high dust environment response. Special gas path design, sampling distance is more than 10 meters, can directly detect negative Pressure or positive pressure -0.5 to 2 kg of gas.

★ Rich man-machine interface. 2.31-inch high-definition color screen, displaying real-time concentration, alarm, time, temperature, humidity, storage and other information; menu interface uses high-definition simulation graphics to display the function name of each menu.

★ Large-capacity data storage function (capacity can be customized), support a variety of storage methods, optional RS485 communication. Standard 100,000 data storage capacity; support real-time storage, timed storage, or only store alarm concentration Data; support the machine to view, delete data, and upload to the computer through the USB interface for data analysis or printing.

★ High temperature gas detection (optional). Optional high temperature sampling cooling filter handle or high temperature and high humidity pretreatment system can detect flue gas at 400 °C. Higher temperature gas detection can be ordered.

★ Three display modes can be switched. At the same time, the four gas concentrations are displayed, and the large font cycle shows the concentration of the single channel gas, and the real-time curve is displayed.

★ Graphical display, reflecting the trend of gas concentration changes over a period of time in a curved form.

• Data recovery function, you can choose to recover partially or completely if you encounter the wrong operation.
