Solid State Carbon Dioxide Sensor

The Alphasense patented carbon dioxide sensor is a world first in CO₂ monitoring:

Requires no power

Operates at room temperature

One sensor measures from 500ppm to 95% CO₂

Small size

Low cost

Simple interfacing

Using the potentiometric measuring principle with our patented silver halide solid state electrolyte, this sensor does not have the high power requirement or high price tag of NDIR technology. This sensor is ideal where low cost and low power are critical for CO₂ measurement.

This sensor is the result of seven years of research and development, and this work continues. While not as accurate as NDIR, and not suitable for IAQ measurements, this sensor is ideal for safety alarms, combustion gas monitoring and high CO₂ process monitoring.
