    Description

    OS-6/SM-EC, Industrial Grade Ozone Controller with Electrochemical Sensor, 0.03-20ppm

    • Heavy duty industrial monitor and controller
    • Rugged spray water resistant enclosure
    • Large backlit digital display
    • Auto-ranging 0.03-20ppm
    • Easy front panel access to set points and relays
    • Easily replaceable pre-calibrated sensor module
    • Set-point controlled relays for generator controls and alarms
    • Front panel generator control cut-off switch for easy maintenance
    • Remote sensor module can be 8m (27') from mains console
    • OSHA 0.1ppm safety limit light
    • Analogue and digital outputs


    The OS-6/SM-EC ozone controller is identical to the model OS-6, only that it will be delivered  with an SM-EC electrochemical sensor instead of a semiconductor sensor plus the suitable sensor interface SM-7.
    The humidity compensated electrochemical sensor is available with  measurement ranges 0.03-20ppm or 1-50ppm. It is not sensitive to VOCs (volatile organic compounds, solvents, etc.).

    The OS-6/SM-EC is an industrial grade controller and monitor for near-earth ozone.
    Its design has been optimised for accuracy, ease of installation, set-up and operation.
    All connections and controls are on the front to allow mounting of the unit before set-up.
    It has a rugged, splash resistant enclosure and connectors for industrial environments.
    Set points for Ozone control relays are digitally controlled and are set to numeric values. This makes precise Ozone control easy to set up, even if Ozone is not currently present.
    Front panel indicator lights display a variety of important Ozone control parameters including when the level exceeds 0.1ppm OSHA limit.
    Generator Control "enable" allows for disabling the generator for maintenance at the OS-6/SM-EC panel.
    There are also user selectable ranges for analogue outputs (4-20 mA and 0-2 VDC)
    The OS-6/SM-EC is equipped with a system failure detection and a user selectable system failure condition timing.

    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 board SM-EC, which is simply used only in place of the old sensor board, and then the device is calibrated again!
