The detector used in these
transmitters is a single wavelength non-dispersive
infrared gas sensor. This technique makes the sensor
highly gas specific; it is not sensitive to other gases
including water vapour, nor is its performance affected by
high concentrations of CO2. The sensor is accurate and has
an excellent long-term stability.The AirCheck
IP65TM has no moving parts that could wear out or fail, so
there is little need for maintenance. As the sensing
element of these transmitters is inherently stable, the
transmitters require calibration only once a year.

The AirCheck IP65TM is a reliable low cost
gas sensor, designed for the monitoring of environmental
CO2 in industrial applications
including protected crops and demand-Controlled
Ventilation. The AirCheck IP65TM ensures accurate and
reliable measurement of CO2 gas concentrations in a robust
low cost IP65 package without using a sampling pump and
can be wall mounted if required. The AirCheck IP65 sensors
are aspirated by a combination of diffusion and convection
within the sensor head. This gas sampling method is
silent, reliable and provides a fast response time.
Convection is used to circulate gas between the sensor
head and the diffusion cell with gas exchange occurring,
by diffusion, at the surface of the diffusion membrane.
Since the gas in the cell circulates within a closed
system, all optics are protected from the ingress of dust.
No additional pumping or filtering of the gas is
necessary.
