SM-500/RME 0-20 ppm: ACTIVE – IN STOCK:
- Smaller form-factor electrochemical-based sensor module with re-zero button, T/RH compensation, and reduced VOC sensitivity. Available for OS-4 with a calibration range of 0-20 ppm – MORE INFO
- SM-7/SM-EC 0-20 ppm: END OF LIFE – NO STOCK REMAINING
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 0.03-20 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.
