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.
- 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.
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.
