The MinIR sensors’ combination of extremely small size, low power consumption and instantaneous warm-up answers the growing demand for sensors which can be integrated into battery or self powered wireless systems. In addition, the small diameter (21mm) of the MinIR sensor makes it ideal for use in probe applications.

The MinIR consumes only 3.5mW in continuous operation while taking 2 carbon dioxide measurements per second. This is 50 times lower power than most standard NDIR sensors.

With measurement ranges up to 100% CO2, the MinIR Sensor can be employed for process control applications such as industrial safety, diving and automotive.
