Feature
★Modular internal structure
1). Adopting a modular internal structure and obtaining a structural design patent
2). It is divided into 3 detection modules, each of which can detect up to 6 gases.
3). It can built-in maximum 18 gas detection
4). The modules are independent of each other and separate the air intake, which can effectively avoid the cross interference of gas to other sensors, and the detection is more accurate.
★ Flexible, multi-pump system
The air supply system of up to three pumps can switch the pump arbitrarily, blocking the loss of the cross-gas to the relevant sensor and prolonging the service life of the sensor
★3.5 inch high-definition color screen
1). The outer casing is made of aviation wear-resistant material
2). Adopt 3.5-inch high-definition color screen, high resolution, wide viewing angle
★High configuration control core
The imported industrial grade sensor, large-size high-definition display, the control system performance is stronger, the operation is more humanized
★Multiple display modes coexist
Support gas concentration data display, gas concentration real-time curve display mode arbitrary switching
★Optional
1). Optional built-in thermal printer for mobile printing at any time
2). Optional equipped with a high temperature probe that can withstand temperatures up to 1100°C
