The ICTO2 measures oxygen based on the galvanic cell principle and does not require voltage input, making it ideal for low-power installations.
If on-board data logging is required, the MFR-Node can be used in place of the V-Node.
The ICTO2 Soil Oxygen Sensor is not affected by saline or sodic soils and can be used in wide ranging applications. For example, in the mining and landfill industries the sensors could be buried in wastes to aid assessment of the effectiveness of covers designed to reduce oxygen flux into the waste.
Soil Oxygen Sensor Features
The V-NODE supports two differential or four single ended sensors. With a 24-bit ADC and stable 3V or 10V excitation voltages, the V-NODE designed for those requiring precision in their analogue measurements.
Use a SAFT Lithium-ion battery for low powered sensors or scale up the power system with a rechargeable Lithium-ion battery and external solar panel.
