Microprocessor- controlled duct ozone sensors AERASGARD® KO3 and room ozone sensors
AERASGARD® RO3 work with a chemical sensor. They are used for the detection of air contamination
by ozone in residential and working rooms, offices, labs, salesrooms, meeting locations and
convention centres as well as in the industrial sector. They measure the O3 content of room air
respectively air inside ventilation or air conditioning ducts and convert the measurement signal
into a standard signal of 0 -10 V. The ozone sensor's service life is depending on the type of burden
and gas concentration.
