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.

ADEV plans and produces probes for the analysis of oxygen to employ in the various industrial fields with problematic different applicative.
The range, based on sensors to zirconium oxide differs for temperature of employment, onerous length of immersion, background, applications and applications to low cost.
It is placed side by side to the extractive models, or to zirconium oxide that paramagnetic or electrochemical and allows the analysis of oxygen in the better solution, beginning from fractions than ppm in volume to 100%.

Honeywell's high accuracy oxygen sensor range employs two ZrO2 discs with a small, hermetically sealed chamber between the discs. The first disc functions as a reversible oxygen pump, which successively fills and empties the chamber. The second disc measures the ratio of the partial pressure difference and generates a corresponding voltage. A heat element produces the 700 °C required for the ZrO2 to operate as an O2 pump. The time needed for the pump to achieve specific minimum and maximum pressures within this chamber provides a measure of the partial oxygen pressure of the environment.
Best Used For:
Industrial process and aircraft on-board oxygen generation system control, automotive exhaust gas diagnostics, service instruments, environmental oxygen monitoring, agriculture, combustion systems and environmental control.
