Moisture Analyzer Moisture Analysis in Solids

Moisture Analyzer

Computrac® Analysis instruments for identification and determination of moisture in liquids and solids excel through their maximum precision combined with robust and solid construction.

Two product lines are available which differ in their general measurement principle:

The "MAX®" line is based on thermogravimetry („Loss on Drying“) where a weight difference after heating determines moisture content, whereas the "VaporPro®" line measures the precise moisture content via a defined extraction of a carrier gas (dried air).

Computrac® Instruments are used in many areas such as plastics, pharmceutical, chemical and food industries for moisture content analysis in powders, tablets, freeze-dried products, granulates, plastic products, paints and coatings and many more.
