Senseair Sunlight R32 (Sense Air)

Senseair Sunlight R32 is an NDIR type micro-flammable refrigerant (R32) gas sensor that uses an infrared LED and an infrared sensor of AKM. 

Designed by using an LED as the light source, this product has achieved excellent safety, high reliability, and a long service life. Its low power consumption and compact and highly accurate specifications enable more flexible product design. 

The built-in ABC (Automatic Baseline Correction) algorithm is automatically calibrated periodically, allowing its use without maintenance once it is installed.  With the increasing demand for sensors, we can provide sensors with performance that can comply with standard requirements for accuracy and response speed.
