Oxygen/temperature lance

Oxygen and temperature analysis for composting

In industrial composting plants, oxygen concentrations and temperature must be monitored in order to optimize the decay process. The oxygen lance, equipped with an amperometric Clark O2 sensor, can reliably measure oxygen concentrations in compost. When connected into a control/ventilation system, the lance can be used to control the ventilation of the decaying materials during the intensive rot stage. This ensures that sufficient oxygen is available for the quick and complete aerobic conversion of the material. The ventilator uses very little power and water loss in the rotting material is minimal. As a result, it is possible to skip the time-consuming and costly step of turning over the rotting material. This reduces the amount of disturbing odours.
Measurements can be taken directly on site when used in conjunction with the AM 40 hand-held meter. The stationary MV 5030 meter can be used for a variety of control solutions. It can also be connected to the event reporting system.

PET 2000

The PET 2000 activity meter can measure the potential absorption of nutrient salts under the same conditions as the actual nutrient salt absorption through the roots. This means that the dissolved salt content is measured in the soil and... ...more Topseller
