Moisture analyzer

is a laboratory

measuring instrument

intended to determine relative humidity for small samples of different materials. MA.R series redefines moisture analyzers standards. This series has been equipped with brand new readable LCD display providing an extra text line for information such as supplementary messages and data, e.g. product name or tare value. The moisture analyzer, using respective pictograms, signalizes currently activated mode, computer connection and functions, both


and service ones.
The MA.R series is enriched with various interfaces: RS232, USB type A, USB type B and Wi-Fi®. The

moisture analyzer

is housed in a plastic casing.

Information system of R series moisture analyzers is based on 6 databases, allowing many operators to operate product database comprising many samples. Collected measurements may be subjected to subsequent analysis.

Collected data is registered in 6 databases:
  • Users (up to 10 users)
  • Products (up to 1000 products)
  • Weighings (up to 1000 weighings)
  • Tares (up to 100 tares)
  • Programs (up to 100 drying programs)
  • Drying process reports (up to 1000 reports)
Exchange of information within the system is performed by means of USB port on bi-directional basis. It is possible to import and export databases using memory sticks.

Direct access to information

It is possible to access functions and databases directly, using keyboard soft keys.
Database – access to databases
Function – access to basic functions
F1 and F2 – programmable function keys and menu navigation keys
Reports – access to database of drying process reports

MA.R Moisture Analyzer - Quick Start


Drying modes

Drying modes

Method for obtaining maximum drying temperature. There are 4 drying profiles: standard, mild, step, fast. The profiles differ by which ensure various dynamics of temperature increase.
Samples drying

Samples drying

Drying process enables to determine moisture content of a given sample by evaporating its free water and other components. The sample's moisture content [%M] is determined by means of precise weighing carried out before and during the drying process. 
Moisture content analysis

Moisture content analysis

Determination of sample's moisture content.
Dry mass determination

Dry mass determination

Determination of product mass after completed technological, physical and chemical processes enforcing product moisture evaporation. RADWAG moisture analyzers are designed to test the moisture content by heating of the samples, which is done using an IR emitter, a halogen or a metal heater.
