Indirect Moisture Methods

Indirect Moisture Methods Indirect methods of measuring moisture use the change in an electrical or structural characteristic of a material as a relationship of its moisture content. Common measurements are changes in capacitance, conductivity, and reaction to radio frequencies. In addition, changes in the absorption of electromagnetic radiation relate to changes in material moisture. Because these methods are indirect, calibration against a known moisture amount is needed. This extra step is often offset by the speed of obtaining a moisture measurement (taking seconds instead of minutes or hours).

Capacitance Based Instruments We offer indirect moisture measurement equipment which we categorize as:

  1. Capacitance
  2. Radio Frequency
  3. Near Infra Red (NIR)

Our staff is experienced in helping select appropriate instruments for specific product and application Requirements.

Radio Frequency Computer & Probe

We offer Capacitance based instruments by Sinar Technology. These include portable bench and hand held units as well as probes. These moisture meters are particularly suited for products such as grains, seeds, and coffee.

The Radio Frequency based equipment covers a wide range of equipment, including specialized probes. The bench top Moisture Computer has a wide range of applications with no conductive materials.

NIR Moisture Analyzers Near Infra Red (NIR) moisture analyzers operate on the principle of the absorption of specific wave lengths of electromagnetic radiation. Water has its own series of wave lengths and can be detected using NIR techniques. We offer on-line and laboratory bench type instruments.

Many of these instruments have been designed to meet the needs of specific industries.
