Composting - a living process!
Composting is an aerobic process (with oxygen). Therefore, a well-aerated compost windrow is a requirement for a proper decomposition. Valuable information about the aerobic decomposition process can be obtained by
measuring the carbon dioxide (CO2) and oxygen (O2) content of the compost windrow, as microorganisms consume oxygen in the course of the decomposition process, converting it into carbon dioxide.
Windrow gas instrument
Especially in the case of unaerated compost windrows, the measurement of windrow gases is important in order to guarantee a sufficient oxygen supply and to better plan turning times. As the microorganisms respire, they consume oxygen while simultaneously forming carbon dioxide. If the oxygen content drops too low, the process may reverse. In addition to high odor emissions, this also produces greenhouse gases such as methane.
With our electronic windrow gas instrument, operators like you can get an overview of current process conditions. The instrument measures up to seven different gases simultaneously and is also easy to use and low-maintenance.
Our standard windrow gas instrument is equipped with three measuring sensors for measuring the most important composting parameters (O2, CO2, CH4).
Technical data:
Standard sensors:
- Oxygen (O2)
- Carbon dioxide (CO2)
- Methane (CH4)
The five additional sensor positions can be equipped with the following sensors, for example:
- Ammonia (NH3)
- Hydrogen sulfide (H2S)
- Additional sensors on request
Digital carbon dioxide measuring device including temperature measuring
Due to the activity in the composting process, oxygen is consumed by the microorganisms and carbon dioxide (CO2) is formed. If the CO2 content rises too high, the process can tip over into putrefaction, the process becomes anaerobic. In order to prevent this, the windrow must be ventilated or turned in time. With our measuring device for carbon dioxide, you quickly get an overview of your composting process in order to be able to react effectively and in time. The gas to be measured is sucked into the measuring device by means of the built-in pump and the suction lance included in the package. The measured values are clearly shown on the display for immediate readout. At the same time, you can record the temperature of your windrows with the included temperature probe to ensure an ideal composting process.
The device is particularly easy to use and maintain, and its fast response time, high accuracy and long sensor life make it the ideal partner for your daily process monitoring.
Sensors:
- Carbon dioxide (CO2; 0 – 20 % Vol.)
- Temperature (0 – 600 °C)
- Electrochemical sensor
