Description
Features
·
- Adopting a modular internal structure and obtaining a structural design patent
- It is divided into 3 detection modules, each of which can detect up to 6 gases.
- It can built-in maximum 18 gas detection
- 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
- The outer casing is made of aviation wear-resistant material
- 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
