The detector is also compatible with catalytic, infrared, semiconductor, electrochemical and other gas sensors. The thickened explosion-proof aluminum alloy shell is designed to ensure stable work in various industrial explosion-proof environments. All-in-one detector can switch 2/3/4 wire system, RS485 and LORA communication by replacing the plug-in module. The special infrared remote control is used to operate, the software is driven by multi-threaded embedded system and programmed by intelligent human-computer dialogue interface, which can meet the various functional requirements of gas detection.
