    Description

    OS-4/SM-EC, Ozone Switch, Ozone Controller, 0.03 - 20ppm

    Acts like a thermostat (2-point controller) to control ozone generators and alarms based on adjustable ozone concentration set-points. Ozone ppm readout via digital meter. Simple and inexpensive.
    Usually the OS-4 is mounted outside the ozone area.
    The OS-4 ozone switch is supplied together wit the digital interface SM-7 and the electrochemical sensor SM-EC

    Practical, inexpensive and time-saving: 
    For recalibration it is no more necessary to return the device to the manufacturer. There is an optional precalibrated accessory available, a  replacement ozone sensor module SM-EC, which is simply used only in place of the old module, and then the device is calibrated again!

    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.
    • The SM-7 sensor interface supplied with a connected 1,60m cable but can also be located up to 8 meters from the OS-4
    • Sensor reading is temperature and relative humidity compensated.
    • Replacement sensor is miniature, low cost, precalibrated and also fits our model OS-6/SM-EC
    • 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 0.1 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 0.03-20ppm.
    • 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.
