The ExplorIR®-W (formerly known as CozIR Wide Range) is a low power, high performance CO2 sensor that can measure up to 20% CO2 levels. It is suitable for measuring high concentrations of CO2 in closed-loop sampling applications or battery operation in portable sampling instruments.

Based on infrared LED technology and innovative optical designs, ExplorIR®-W combines the accuracy of NDIR technology with wide-range CO2 measurement in a flexible package for OEM integration.


  • 0-20% carbon dioxide measurement
  • Durable, low power consumption
  • Ideal for battery powered systems, or harsh, rugged environments
  • Industry standard serial communication
  • Simple to install, pre-calibrated and ready-to-use


GC-0006 ExplorIR®-W 20% CO2 Sensor Only - for integration into high-volume OEM products. Contact us directly for wholesale pricing on large quantities of this sensor.
