★ It can detect 1 to 5 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 water vapor and dust, can be used in high humidity and high dust environment, and respond quickly; special gas path design, sampling distance is more than 10 meters, can be directly detected Negative or positive pressure -0.5 to 2 kg of gas.

★ Rich man-machine interface. The 2.5-inch high-definition color screen displays real-time density, alarm, time, temperature, humidity, storage and other information; the menu interface uses high[1]definition simulation graphics to display the function names of each menu.

★ Large-capacity data storage function (capacity can be customized), supports a variety of storage methods. 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, upload to the computer through USB, RS232 interface or infrared communication for data analysis or printing.

★ A variety of communication interfaces and printing functions. Infrared communication interface (optional), RS232 interface (optional), USB interface automatic identification, optional external micro Bluetooth printer.

★ 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 800 °C. Higher temperature gas detection can be ordered.

★ Personnel fall alarm function (optional).

★ Large memory 16G, 32G (optional).

★ Three display modes can be switched. At the same time, five 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.
