Gas Detector Controller is a compact and lightweight gas monitoring device specially designed for small-space applications such as small workshops, laboratories and equipment rooms. It is equipped with a user-friendly Chinese/English LCD display, which supports switching between two languages for easy debugging and operation, and can clearly display the installation location of each device, greatly simplifying on-site management and maintenance work. With a lightweight and portable enclosure made of high-quality V0-rated flame-retardant material, it not only has excellent safety performance but also is durable, capable of adapting to various harsh small-space environments. The device supports XBUS 2/4 wire protocol, which enables easy and flexible wiring, reducing the difficulty and cost of on-site installation. Built-in RS485 and TTL ports are compatible with multiple mainstream communication protocols, facilitating seamless connection with other monitoring equipment. Unlike other models in the series, it has a built-in IoT module for direct IoT transmission, eliminating the need for additional configuration of wireless equipment, which is perfect for small-scale scenarios that require simple installation, convenient operation and reliable real-time gas monitoring.
