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.
SM-4 sensing module located up to 100 meters from the OS-4
