In modern HVAC, industrial refrigeration, and safety monitoring systems, refrigerant leaks not only affect equipment efficiency but can also pose safety hazards. Traditional detection methods are often limited by oxygen dependence, susceptibility to poisoning, and slow response times, making it difficult to meet the industry's demands for high reliability and long lifespan. To address this, Tensensor has launched the GRT510 refrigerant detection module based on the principle of nondispersive infrared (NDIR), redefining the new standard for refrigerant safety monitoring with its intelligent, stable, and efficient detection performance.

GRT510 Refrigerant detection module

Core Technology, Precise Detection

    The GRT510 employs advanced NDIR infrared absorption detection technology, achieving highly selective detection of common refrigerants such as R454B, R32, and R290. It is oxygen-free, resistant to moisture interference, and features self-heating, making it suitable for high-humidity environments. Its resolution reaches 0.1% LFL, and its response time to the alarm point is less than 10 seconds in a 25% LFL environment, truly achieving "second-level response and precise early warning."

Intelligent Integration, Flexible Communication

    The module supports RS485 communication, is compatible with the Modbus RTU protocol, and can be customized with UART or PWM output, easily connecting to various industrial control systems and IoT platforms. Built-in temperature and humidity compensation mechanisms ensure stable and reliable data output. Simultaneously, the device features a life counter and early warning function, continuously monitoring the device's health status for preventative maintenance.

Rugged and Durable, Applicable to All Scenarios

    Operating temperature range -40℃~80℃, humidity 0~100%RH, adaptable to extreme environments; compact and lightweight casing (75.4×57×21.5mm), flexible installation. Certified by UL/IEC 60335-2-40:2022, this product is safe, reliable, and has a service life of over 15 years, making it an ideal choice for industrial safety and HVAC monitoring.

Wide Applications, Prominent Value

    HVAC Systems: Real-time monitoring of refrigerant leaks in air conditioning and refrigeration equipment, ensuring efficient and safe system operation.

    Industrial Safety Monitoring: Used in chemical plants, cold storage facilities, production lines, etc., to prevent the accumulation of flammable refrigerants.
