PMV 50 PLUS moisture analyzer is an advanced solution for the measurement of moisture content of samples containing a significant amount of moisture (up to 100%). The drying process is carried out by means of microwaves which enable to evenly heat the whole sample's volume. The PMV 50 PLUS, when compared to standard moisture analyzers, significantly shortens the drying time.

The PMV 50 PLUS microwave moisture analyzer can be successfully used wherever materials containing large amounts of water are dried, for example: dairy products, fish, meat, fruit products, syrups, creams, liquid resin.

The sample is placed in the drying chamber on a glass fiber 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 the 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 PLUS microwave moisture analyzer is equipped with a temperature sensor and enables to the monitoring device to power in order to prevent exceeding the boiling point during the process. Preset microwave power is displayed on the indicator throughout the drying procedure.

The PMV 50 PLUS moisture analyzer is based on an advanced-class Y series system intended for laboratory balances. Expanded 16 GB memory enables saving and storing sophisticated reports and time and statistical graphs. Wireless communication improves ergonomics and operation safety. Wi-Fi® enables sending data between the moisture analyzer and a mobile device. Large 5.7’’ touch screen guarantees the comfort of operation. Proximity sensors ensure touch-free access to user-specified operations.

For each purchase of the PMV 50 moisture analyzer the customer is supplied with:

• 60 glass fibre filters of ø 90 mm,
• a sample of sodium chloride 10% ±0,5% to determine the correctness of the operation at the workstation,
• a service concerning the determination of drying parameters for five customer-selected samples carried out by RADWAG employees.

The results obtained using the moisture analyzer (the final result of the drying process):

• % M - the mass loss in %; displays the mass change recorded during the drying process, expressed as a percentage,
• % D - the dry mass obtained during the drying process, expressed as a percentage; the result is the portion of the sample that remains on the weighing pan after the moisture has evaporated,
• % R - the ratio of moisture content to dry mass, obtained during the drying process, expressed as a percentage; the result is the portion of the sample that evaporated during the drying process,
• g - the sample mass after drying.

Functions include:

Drying modes, samples drying, moisture content analysis, dry mass determination, microwave drying
