NDIR R1234yf Refrigerant Gas Sensor
AM4207 SeriesAM4207 Series

Cubic AM4207 Series is an NDIR R1234yf refrigerant gas sensor designed for reliable and accurate refrigerant gas leak detection. The sensor delivers high accuracy, long-term stability, and a long lifespan, making it a robust solution for cold chain transportation applications.

Built on mature NDIR sensing technology, the sensor provides strong selectivity to R1234yf and excellent resistance to other gases, especially to CO2. The sensor minimizes CO2 interference from the fruit and vegetable cold chain transportation environments where high-level CO2 accumulates, ensuring stable performance even when CO2 concentrations fluctuate.

An integrated automatic heating function helps prevent condensation and ensures stable operation under environments with rapid temperature and humidity changes. A built-in reference channel and self-compensation mechanism further reduce drift caused by optical aging and environmental variation, supporting long-term measurement consistency and reducing false alarms. The sensor features fast response capability, enabling timely and dependable detection for early warning systems. Designed for easy integration, the sensor features a compact form factor, suitable for installation inside refrigeration equipment.

Compliant with the IEC 60335-2-40 standard, Cubic R1234yf refrigerant sensor provides a reliable sensing solution for cold chain transportation field.
