The capacitive measuring principle utilises the different dielectric coefficient (electric field permeability of a material) of dry, nonconductive material (approx. 2-10) and water (approx. 80). The wetter the material, the higher is its dielectric coefficient. A capacitor makes this coefficient measurable. This capacitor

There are different type of capacitance meters are available which allows you to measure the capacitance directly between 0.1 Pico farad and 20 microfarads. The unit of capacitance is farad represented by a letter ‘F’. There are several methods to measure the capacitance but the most accurate method is the bridge method.
Depending on the sophistication of the meter, it may display the capacitance only, or it may also measure a number of other parameters such as leakage, equivalent series resistance (ESR), and inductance. For most purposes and in most cases the capacitor must be disconnected from circuit; ESR can usually be measured in circuit.
