PMV PLUS Moisture Analyzers

microwave moisture analyzer can be successfully used wherever materials containing large amounts of water are dried. These materials are, for example, dairy products, fish, meat, fruit products, syrups, creams or liquid resin.


The sample is placed in the drying chamber on a glass fibre filter. At the bottom of the chamber there is one end of the waveguide from where the microwaves are emitted. Upon process start, microwaves are equally distributed on the filter’s surface and dry the sample. The moisture content is determined on the basis of the mass loss obtained during drying.


A respective drying program is selected depending on sample mass and its chemical composition. The average duration of this process depends on the type and mass of used substance, and takes 1 to 10 minutes. In contrast, drying using the traditional halogen moisture analyzer takes 5 to 40 minutes.


The PMV 50.5Y microwave moisture analyzer is equipped with a temperature sensor and enables to monitor device power in order to prevent exceeding the boiling point during the process. A preset microwave power is displayed on the indicator throughout the drying procedure.

• 60 glass fibre filters of ø90 mm,
• a sample of sodium chloride 10% ± 0,5% to determine correctness of the operation at the workstation,
• a service concerning determination of drying parameters for five customer-selected samples carried out by RADWAG employee.
