MOZ 300/500

The portable MOZ300/500 ozone measurement device is designed to monitor and measure ozone in a wide variety of different applications. Ozone concentrations can be shown on the LCD display in either ppm or mg / m³. User-defined upper, lower, and target values can be displayed. The device triggers an acoustic alarm if the ozone concentration exceeds or falls below these values, transmitting a signal to the relay controller.

MOZ 300/500

Using the 0/5 V output, the MOZ300/500 device can activate an externally connected relay which controls an ozone generator or an external system. The MOZ300/500 measurement device can be permanently mounted using the optional wall bracket, or used as a mobile handheld device. The MOZ300/500 can be equipped with a variety of measurement sensors (different measurement ranges). The MOZ500 is also designed with a data logger function.


  • Simple use – Thanks to its handy size and easy
    to read display

    Mobile use – The lithium battery provides up
    to 8 hours of mobile use

    Acoustic alarm – If ozone levels exceed the limit value, the unit triggers an acoustic alarm or an
    alarm via the interface

    Compatible – The integrated analog output
    allows the unit to control external devices
    (e.g. ozone generator)

    Flexible – Different measurement ranges
    available by simply exchanging the sensor
