The TH300 soil moisture probe is a fast, accurate and completely portable soil moisture probe. Based on TH2O, Theta probe technology, the instrument uses SM150 soil moisture sensors. Results are in water by volume (± 2.5%). The probe readout stores over 1000 data points, which can be downloaded to a PC and imported into spreadsheets. The instrument minimizes soil disturbance, preserving the original soil structure around the measurement rods. It is easy to insert and install whether at the soil surface or at depth. The probe is dual-purpose – it can be used both with the hand-held moisture meter for instant moisture readings, or left in situ for data logging of moisture and temperature. Dynamax
