The CarbonOxy is a unique device for measuring CO2 and O2 on a Euro Printed
Circuit Board (PCB). Carbon Dioxide is measured using the dual wavelength
technique (NDIR - Non-Dispersive Infra Red) while Oxygen is measured using
Zirconium Oxide. This combination ensures a quick response time along with
elimination of intereference from other gases.
With various DIP switches on the circuit board, the response time for the
analyzer can be adjusted between 1 to 10 seconds. It is possible to do automatic
temperature correction or zero point adjustment can be made. The entire circuit
board is constantly monitored by a microcontroller and LEDs in various colors
can indicate alarm states and out of range values.
The power consumption of the combination is maximum of 6 watts and hence is
suitable for a portable, compact measuring device. All electronics meet the
latest European EMV regulations.
