OS-4 Ozone controller
 
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 inexpensive.

Features:

    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 standard exceeded.

Typical Applications:

  • 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.
