Dissolved Oxygen Measurement

MJK Oxix provides data allowing you to control the amount of oxygen, thereby obtaining the optimal environment for biology process.

The right oxygen level makes your process more efficient, and ensures that you are not wasting energy on unnecessary operating of blowers and aerators.

Mounted on the float ball the Oxix sensor will at any given time measure the oxygen level on the same depth of the basin, providing excellent measuring repeatability.

The sensor is self-cleaning if you choose to use the built-in water / air spray nozzle; that will keep the sensor working with a minimum of manual maintenance.

Read the values on the display, or have data transferred directly into SCADA using the built-in ModBus capability.

    Oxix measures the oxygen level based on fluorescence, no oxygen is spend during the process

The right level of oxygen in the tanks and basins creates the perfect environment for the microbes in the waste water process.
The right amount of oxygen will reduce the operating cost of the plant, the wrong oxygen level can cost extra process hours or days – or ruin the process.
Oxix is developed by MJK to provide exact oxygen measurement using a fluorescent sensor, so no oxygen is lost on the measurement.
Oxix has a built-in jet cleaning nozzle, ensuring the small sensor window is clear, this provides the optimal long term effectivity.
Measured values are stored in the built-in data logger, can be read on the multi-language display.
Data can also be transferred to a SCADA system.
Oxix works well in network with similar transmitters, such as Susix and MagFlux.

For measuring the oxygen level on the water distribution for endusers, the Oxix is a well-proven stable solution, with no maintenance on the sensor, and 3 years warranty on the sensor.
The sensor is a 2 part sensor, consisting of oxygens measurement and a converter, displaying the measured values on the clear display combined with transferred as 4-20 mA.
The built-in cleaning nozzle can be used with water or air, and virtually eliminates any other maintenance of the sensor window.

Measures oxygen based on optical fluorescent measurement, a very trustworthy measurement.
Oxix can be mounted on a floating ball for surface measurement or mounted on a pipe.
The right level of oxygen, the mg/L, saturation and the temperature are pivotal to provide the optimal FCR.
A built-in cleaning nozzle will keep the sensor window clean without manual work erquired.
There are several display options, the converter and display provides the most complete solution, but for a quick on-site readout, use the simple LCD display.
Oxix provides Modbus or a 4-20mA signal which can provide the measured data directly into feeding system software.
2 relays are built-in to assist the control of the oxygen levels, or to be used for external alarms.
The display can store and present data from up to 4 different Oxix devices (or other MJK products) on a distance of up to 1000 m.


Oxix mounted with a ball float provides uniform measurement of the dissolved oxygen level in the aeration basin.

The ball float ensure that the Oxix sensor measures at a constant level from the surface, not influented by a changing level in the basin.

This sensor mounting principle insure an efficient and reproducible measurement of dissolved Oxygen in the aeration basin.

Land based fish farms are very dependent on the dissolved oxygen level in the ponds.

When fish eat, consumption of oxygen raises, hence this is an important parameter. The measurement of the dissolved oxygen is tranmitted to either a nearby outdoor mounted display and data logger, or in many cases directly to the SCADA system.
