The Thetaprobe is also available in the form of a profile probe for use in thin-walled tubes that are installed in the soil. The profile probe is fitted with 6 measuring elements with a measuring range of 100 cm so that the soil moisture content can be measured at different depths within a vertical soil profile. The probe measures with an accuracy of ± 3% in a thin-walled tube and has a measuring volume of ± 1.5 litres at each profile depth. The profile probe can be used as a portable system by using the soil moisture meter or as a fixed system by using a profile probe in combination with a datalogger. The thin-walled tubes can be placed in the soil with the use of a special auger kit.
Benefits Profile Probe
- Soil moisture content - not just trends
- Low salinity and temperature sensitivity
- Portable meter option for convenient multi-site measurement
- Out of the box solution - supplied with soil calibrations for common soil types
- IP68 protected connectors for versatile connectivity
- Uses access tubes for easy probe insertion and removal
Profile Probe with Hand Meter
The measurement values are shown on the display of the soil moisture meter (art. no. 14.26.02) and can be stored in the memory (including time and sensor location). These data can be read on a PC. The meter comes with built-in conversion characteristics for mineral and organic soils. The software allows a further 5 soil specific calibrations to be introduced. The meter has no temperature indication.
If the moisture content is measured of other materials the meter will give an output signal in millivolts. If a series of soil moisture measurements is required the soil moisture sensors can be connected easily to a datalogger.
Datalogger for Profile Probe
This datalogger with 6 analogue channels is a dedicated datalogger optimised for use with soil moisture sensors. It can be used with combinations of Thetaprobes and also accepts rain gauge and soil temperature probe inputs. Up to 16000 readings can be stored in the memory.
