The KSK oxygen probe is designed to measure the content inside the compost heap in both open and covered composting plants.

The measuring probe is in the form of a lance 1000 mm long and contains an oxygen sensor.

The end of the lance driven into the compost has a rounded head, so that the compost components encountered "on the way" do not stick into it. The probe is powered by direct current with a rated voltage of 12VDC or 24VDC, while the data on measurements are transmitted, depending on the version of the device, by wired or wireless.

  • The device is easy to use
  • Wired device with optional wireless data transmission
  • The device is made of appropriate quality stainless steel ensuring safe operation in highly acidic conditions
  • Constant data transfer in real time


Years of innovation

Thanks to many years of technological improvement and thoughtful design, all KSK devices offer unsurpassed quality and flexibility.

The oxygen probe in the version with wireless data transmission can be equipped with two network interfaces depending on the demand. In the case of local operation of the installation, data is transferred from the lance to the device installed in the controller cabinet (CPU - more here ...). In order to increase the range, the communication can be extended with up to 8 repeaters.

In the wired version, the data signal is realized in the analog 4-20mA or digital form via the CAN bus.


The second solution is to transfer data directly to the cloud via the LoRa network. This type of transmission allows you to cover a huge area with a radius of several kilometers in a star topology with one base station or through the public network. Data can be transmitted directly to an external server and managed there (cloud solution). Alternatively, the installation can be local - data are made available directly from the base station to the supervisory system.

In the data cloud solution, the user has access to a data server and a mobile application that allows remote monitoring of all "his" devices. The application allows you to set alarms, view graphs, etc. Access from anywhere on Earth.
