AquaCheck Sub-surface Probes

The AquaCheck sub-surface soil moisture probe offers capacitance based soil moisture measurement offering up to six depths or sensors per probe. The probe is dependent on a compatible external logger or remote transmission unit and is available in either SDI-12 or MODBUS configurations.
General Specifications: A capacitance based continuous logging probe. Probe lengths from 400mm to 1200mm. Up to 6 soil moisture and 6 soil temperature sensors depending on the probe length. Shaft diameter: 32mm. Up to 6 sensors or depths per probe. Can be used for pastures or other sub-surface measurement applications. Communication Interface options: SDI-12 (serial data interface, 1200bd), MODBUS, 2400bd Compliancy: CE certified. Supplied with a 5m 3-core cable.	Technical Specifications: Voltage input: 4-12V for standard models; 9-16V option available on BASIC II (on request). Power requirement: 10uA (0,01mA) during idle; 20mA for 2 seconds during measurement. Sensor Spacing: 10cm or 20cm (fixed). Sensor reading count: approximately 32000 for air and 1000 in water. Sensor resolution: Approximately 13 bits. Temperature Sensor: 0-51 Deg C, steps of 0.2 Degrees. External power supply required.
