Carbon Dioxide

The Alphasense patented Carbon Dioxide sensor is a world first in CO2 monitoring:

• Requires no power
• Operates at room temperature
• Measures from 5000ppm to 90% 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 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.
