The Tianyan series fixed gas detector, designed by Yourui’an Technology for users, is a professional high-end gas detection product. This product utilizes high-performance core sensor technology and intelligent algorithms such as long-life, high-precision, and automatic zero adjustment, boasting 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, which are then transmitted 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 connected to an Anpar server, the device can achieve remote monitoring, remote alarm value setting, and remote calibration functions
