Product Information

TheJamesAquaprobe™ represents a break-through in modern moisture measurement technology. By utilizing the latest microwave and microprocessor technology, theAquaprobe™ can determine the soil moisture content of different types of soils and other fine aggregate. Simply insert the five prongs in the soil to be measured and review the percentage moisture on display.   A special guide is supplied to assist the user with inserting the prongs in particularly dense soil.

TheAquaprobe™Microwave Soil Moisture Meteruses a five prong sensor to measure the complex dielectric constant of the material encompassed by the outer four prongs. As the dielectric constant of water is four to eight times greater than most natural soil types, changes in water content directly affect the sensor output. This output is then converted by the integrated microprocessor and moisture content is displayed directly as a percentage of dry weight.  An average of five to ten readings is normally taken in order to ensure a valid reading, especially as water does not distribute itself evenly for many types of materials. 

The basic unit comes pre-calibrated for Lean Clay, Silt, Sand （Ottawa Sand and SP sand） and general type of Silty Sandy soil.  These soils represent the most commonly found types.  This makes the basic unit the economical choice when evaluating soil moisture levels.

The complete system includes equipment to create custom calibration curves for different types of soil.  The instrument can be programmed with up to ten different materials by the user. For highest accuracy, the unit should be programmed for the material being tested. Simple to use Windows™ software is provided for calibrating the unit to the various materials.

Finally, theAquaprobe™ instrumentation unit can store over 150 readings. Storage is complete with the time and date for future reference. Data can be recalled via USB interface to a personal computer running Windows™.
