Ozone Sensor Unit
The ozone sensor unit is either of the following:
-
Science Pump Corporation (SPC) Model ECC-6A ozone sensor
-
Droplet Measurement Technologies (DMT) Model Z ozone sensor
The sensors are based on chemical reaction cells. The type of the
sensors is electrochemical concentration cell (ECC). Air is sampled
flow (by using a pump) and it goes to a reaction cell, in which the
sampled ozone reacts in a solution, and the current developed in the
reaction is detected and measured with an ozone interface. The ozone
sensor units are thoroughly discussed in the sensor manufacturers’
manuals (see section
) and Performance
Review Literature listed in Appendix D
The main parts of an SPC ECC-6A ozone sensor are seen in
. Model Z ozone sensor is similar to the SPC sensor. Refer to the
sensor manufacturer’s manuals for more detailed information.
