Tips: Why is this sensor suitable for HVAC monitoring and refrigerant leak detection?

This refrigerant gas sensor is ideal for HVAC monitoring and refrigerant leak detection due to its precise NDIR technology, which accurately measures hydrofluorocarbon (HFC) concentrations while remaining unaffected by oxygen levels or moisture. Its 0~100% LFL detection range, 1% resolution, and fast T90 ≤30s response ensure quick identification of even small leaks, preventing inefficiencies, environmental harm, and safety risks. Designed to operate in a wide range of temperatures (-20°C to 70°C) and humidity (0~95% RH), the sensor is reliable in diverse environments. Its low power consumption (<85mA) supports continuous monitoring with minimal energy costs, while the 10-year lifespan and compatibility with serial port and DAC outputs make it easy to integrate into automated HVAC systems, enhancing safety and efficiency.
