Ozone Switch [OS-4]

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.
