R32 And R454 Refrigerant Infrared Sensor

The NDIR technology used in Senseair Sunlight products ensures that the sensor is protected from poisoning, while the optical solid-state design makes it physically rugged and resistant to vibration. With our automatic baseline correction feature, you can install and forget about the sensor and maintain high accuracy over a lifetime of more than 15 years.
