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 effective. Ships with SM-7/SM-EC 0-20 ppm sensor module.

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, and pre-calibrated.
  • 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.
