At the same time, it can detect 1 to 4 kinds of gas, and the unit is free to switch.

Optional units: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.,

In pump suction measurement, integrated water vapor, dust filter, quick response and support long distance sampling

The built-in water vapor, water vapor and dust dust filter to prevent damage of sensors and instruments, can be used for high humidity, high dust environment; sampling distance greater than 5 meters, the special air route design, direct detection; negative pressure or positive pressure gas -0.5 ~ 2 kg, had no effect on the measurement results.

Rich man-machine interface

2.31 inch high-definition color screen display, real-time alarm, concentration, time, temperature, humidity, storage, communication, power, state of charge, concentration units,

Gas molecule type, gas name and other information; menu interface using high-definition simulation graphics display the function of each menu name.

Large capacity data storage function, support a variety of storage methods

The standard 100 thousand data storage capacity, larger capacity can be customized; support real-time storage, storage time, or only alarm concentration data; support the view, delete data, or data can be uploaded to the computer through the USB interface with PC software, data analysis and storage, print optional RS485 communication.

High temperature gas detection (optional)

Optional high temperature sampling temperature filter handle or high temperature and humidity pretreatment system can detect 400 degree temperature of the flue gas.

Three display modes can be switched

At the same time display four kinds of gas concentration, large font cycle shows the concentration of single channel gas, real-time curve display.

Graphical display

In the form of curves, it reflects the trend of gas concentration in a period of time.

Data recovery function
