MPKit Soil Moisture Instant Reading Kit
For portable and convenient measurement of volumetric soil moisture content in sports fields, irrigation monitoring, mine sites, and landfills.
The MPKit is a reliable and convenient portable soil moisture sensor. The MPKit does not need calibration and is not affected by temperature. The sensor needles are stainless steel and are embedded in a reinforced body.
The MPKit has been reliably used in the softest soils to the hardest, most stony soils. The MPKit is used with the KD2Pro or the MTN02 when measuring soil thermal properties.
MPKit Soil Moisture Instant Reading Kit Features
OPTIONAL: The MPKit can also support the MP306B sensor for pots in glasshouses or growth cabinets
The MP406B can be used to measure the soil moisture for scientific research or irrigation management. In either situation the MP406B can:
The MP406B Moisture Probe can also be used to measure the moisture content in many materials such as soil, food and materials used in roadway and building construction.
The MPKit is a very suitable substitute for the Neutron Probe for irrigation scheduling
A series of holes are augered to the top (20 cm), middle (40 cm) and bottom (60 cm) of the root zone. The augered holes have a 50 mm PVC tube inserted. This enables routine measurement of soil moisture at the same location and depth for irrigation scheduling.
The MPKit, when used in this manner has the same application as the Neutron Probe.
The MP406B has a high frequency moisture detector, which uses the standing wave principle to indicate the ratio of two or more substances forming a body of material, each substance having a different dielectric constant (Ka).
The moisture measurement of the material is based upon the fact that in a water:soil:air matrix, the dielectric constant is dominated by the amount of water present. Then the soil water content can be measured exactly because changes in water content of the soil result in changes in the dielectric constant of the soil.
