MST3000+handheldRapid moisture measurementInstrument suitable forsoilTemperature and humidity sensor SMT 100 sensor for quick reading. The operation is exceptionally simple: press a button, and the measured value will be immediately displayed on the LCD screen. The automatic shutdown function prevents unconscious battery consumption. MST 3000+can be used for direct independent measurement of all soils and substrates. But when using this measurement method, it is important to consider that the same measurement value from the sensor can only be obtained under the same environmental conditions (soil density, insertion depth). Therefore, it is strongly recommended to measure multiple times and take the average of the results.
