The Tianyan series fixed gas detector is a professional high-end gas detection product designed and launched by Yourui’an Technology for users. This product utilizes high-performance core sensor technology and intelligent algorithms such as long-life, high-precision, and automatic zero adjustment, featuring excellent output performance and good temperature and humidity characteristics. It is suitable for continuous detection of combustible and toxic gas concentrations in industrial environments. Its main functions include converting the gas concentration detected on-site into corresponding standard signals, and then transmitting these signals to upper computers such as PLCs, DCSs, and alarm control hosts for unified display management and control, thus forming a powerful intelligent gas detection and alarm control system. The Tianyan series fixed gas detector is equipped with a built-in relay that can control peripheral sound and light alarms, fans, solenoid valves, and other devices. If the device is connected to the Yourui’an server, it can achieve remote monitoring, remote setting of alarm values, and remote calibration functions
