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).

We offer indirect moisture measurement equipment which we categorize as:

  1. Near Infra Red (NIR)
  2. Radio Frequency
  3. Lab Moisture Measurement

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

 

Finna-Sensors-OMNIR-On-Line-Near-Infrared-Moisture-SensorPartnering with Finna Sensors, we also offer a range of Near Infrared, Radio Frequency, and Lab Unit equipment.

Near Infrared (NIR) moisture sensors are able to measure the surface moisture of a product by reflecting light and reading the wavelengths that come back. Water has its own series of wavelengths and can be detected using NIR techniques.

Radio Frequency moisture sensors are able to penetrate into the applications with a known temperature and distance from the sensor.

Lab Unit equipment involves testing a collected sample. The bench topFinna-Sensors-MCPC-Almond-Moisture-Analyzer has a wide range of applications with non-conductive materials.
