|Acts like a thermostat to control
ozone generators and alarms based on adjustable ozone concentration
set-points. Ozone ppm readout via digital meter. Simple and
Easy to install. Minimal adjustments. Sensor is in a replaceable
precalibrated module. Separated by a cable, the instrument is not in the
high ozone area. Sensor reading is temperature and relative humidity
compensated. Replacement sensor is miniature, low cost, precalibrated and
also fits our A-22. Operates from 12-24 VDC or from AC adapters available
worldwide. Alarms, data loggers, and other accessories available.
Programmable turn-on and turn-off set-points. Indication when .1 ppm safety
- Monitor ozone levels in treatment storage areas for
fruits, vegetables, and other agricultural products. Monitor ozonated HVAC
systems. General monitoring at .03-20 ppm.
- Control the output of ozone generators using the
set-point controlled relay in the OS-4.
- Use as either ozone leak alarm or ozone failure alarm
for all sizes of ozone generators.
