Soil temperature Th2 Measuring range -50°C...+70°C Accuracy ±0,1 K at 0°C ±0,2 K at ± 20°C ±0,1 K at ± 40°C Sensitive span Length 15 mm ,Ø 5 mm Sensor position 10 mm from tip Casing of tip Stainless steel, IP68 Dimensions Length 80 mm, Ø 6 mm Cable length 10 m Benefits Highest accuracy Minimised soil disturbance Punctual temperature pick-up Maintenance-free and durable Cable strain-relieved Three temperature sensor types available Available sensor types: Pt100 Standard 4-wire probe For cable lengths up to 200 m Linear signal output Thermistor 3-wire connection for data logger applications Non linear but high-resolution output Excellent long-term stability Cable length max. 40 m Pt1000 3-wire but with linear output Cable length max. 20 m Th2 Soil temperature probe The durable, water proof temperature probe for soils, fluids, gases. The thin body and sharpened tip reduce the soil disturbance when installed and ensures a good thermal contact to the soil. A heat conducting filling inside improves the thermal conductivity from the casing to the probe - for a fast response punctual temperature pick-up and minimised cable temperature influence. Item with Pt100 1/3 B with Thermistor with Pt1000 1/3 B Art.no. Th2-h Th2-f Th2-t Th3 Soil Temperature Profile Probe to measure the temperature profile in soils in the depths 5, 10, 20, 30, 50 and 100 cm. Inside a tube made of glass-fibre reinforced plastic 6 temperature sensor elements are placed in different depths. Each sensor element has direct contact to a stainless steel ring which ensures that each sensor has direct contact to the soil. Measuring range -20°C...+50°C Accuracy ±0,1 K Resolution 0,034°C Output signal 6 x 0...1 V Supply 6 ... 18 VDC Dimensions Length 102 cm, Ø2 cm Cable Length 1,5 m, 8-pin plug M12, strain-relieved, with plastic protection tub Tube GRP glass-fibre reinforced plastic, embedded stainless steel rings, conical tip Options Probe with SDI-12 output and 4-pin plug M12 Benefits – – – – – – – – Get a temperature profile with only one probe 6 analogue signals 0 ... 1 V Optionally with SDI-12 Minimised soil disturbance Probe and cable completely buried, thus no influence of the ambient temperature Punctiform temperature pick-up Excellent thermal contact through thin-walled stainless steel rings Robust and maintenance free Item Probe with 6x0...1V Probe with SDI-12 Art.no.

Laboratory evaporation method for the determination of pF-curves and unsaturated conductivity The evaporation method according to Wind/Schindler is a simple and fast technique to determine retention curves of soil samples in standard 250 ml soil sampling rings. The unsaturated Benefits – – – – – – – – – Simple and flexible handling Low time and cost expenditure Expandable Small size for easy transportation The water retention curve is determined with high quality even close to saturation The hydraulic functions are reliably assured by the large number of taken readings Simultaneous and accurate measurement of water retention curve and hydraulic conductivity Suitable for all soils (as long as Tensiometers can be installed) No special requirements for the measuring location beside possibly constant evaporation conditions during a measurement conductivity is determined by measuring the soil water tension with miniature Tensiometers in two levels inside the sample, and then correlated to the soil water tension or the moisture content. Durner and Peters developed the robust correlation procedure to link the hydraulic functions (SHYPFIT 2.0, Peters and Durner, 2006b). The data is fitted to a selectable standard model, i. e. van Genuchten/Mualem, bimodal van Genuchten/Mualem or Brooks and Corey. The Model parameters can be set before, during or after a measuring procedure. Thus, the results are verified and the values for dry range and saturation are calculated according to the selected model. Limits – The operating range is limited to the measuring range of the Tensiometers – Poor resolution of the hydraulic conductivity near saturation (especially in sandy soils) Execute a measurement If a sample unit is placed on the scale the software automatically starts the weighing menu. If more than one sample is tested at a time each sample is placed on the scale in turn, for example twice a day. The software automatically recognizes each sample unit and stores the weight in correlation to this sample. A maximum of 20 samples can be tested simultaneously. Independent from the weighing the soil water tensions are automatically measured. Pressure transducers and electronics are housed in the sensor unit, and all sensor units are linked with the tensioLINK bus to your PC for continuous logging of the soil water tension. Hyprop The advantage compared to other methods is that the hydraulic properties are determined during a natural drying process of the soil. Hyprop’s outstanding features are the simple handling and the modular setup. For a start up you just need the HYPROP starter set and a scale. Existing laboratory scales, minimum requirements are a serial connection and a measuring range of 2000 grams, can be integrated. This set can be extended to up to 20 sample units. Together with the correlation procedure you get a truly practical method which offers extraordinary results in the determination of hydraulic functions with low measuring expenditure.
