Moisture Analysers & Meters

Moisture analysers are specialist laboratory instruments for determining moisture content in solid or semi-solid materials. They are used to rapidly heat small food samples with built-in halogen lamps which can then be weighed precisely (usually in grams) using a loss-on-drying technique.

In this technique, a sample of material is weighed, heated in an oven for an appropriate period, cooled in the dry atmosphere of a desiccator, and then re-weighed. If the volatile content of the solid is primarily water, the LOD technique gives a good measure of moisture content.

The manual laboratory method is relatively slow, so automated moisture analysers have been developed that can reduce the time necessary for a test from a couple hours to just a few minutes. These analysers incorporate an electronic balance with a sample tray and surrounding heating element. Under microprocessor control the sample can be heated rapidly and a result computed prior to the completion of the process, based on the moisture loss rate, known as a drying curve.

We supply a range of A&D Moisture Balances and the Adam PMB Moisture Analyser. They all contain halogen lamps - contact us if you need replacement lamps.
