Introduction
The Myco2 carbon dioxide monitor is a high
performance infra red gas sensor designed for the environmental
monitoring of carbon dioxide, particularly in horticultural
applications such as mushroom farming.
The unit uses a special non dispersive dual
wavelength infra red sensor unit which has no moving parts. This
ensures the long term stability of the instrument. The sensor is
highly gas specific and insensitive to other gases and water
vapor. The gas enters the sensor by a combination of diffusion
and convection within the sensor head. This method is silent
reliable and provides a fast response.
( Convection is used to circulate the gas
between the sensor head and the diffusion cell - gas exchange
occurs by diffusion at the surface of a diffusion membrane.
The gas in the cell circulates within a
closed system so that the optics are protected from the ingress
of dust and pollutants. No additional filtering or pumping of
the gas is required.
The instrument is enclosed inside a tough
plastic enclosure rated IP65 against the ingress of water and
dust further increasing its long term reliability. Alarm levels
are set on an internal dipswitch. ) |
