The MA R Moisture Analyzer is designed for routine laboratory determination of moisture content, dry mass and related parameters using the gravimetric drying method. The series combines precision weighing with programmable drying procedures in a straightforward operating environment intended for everyday laboratory use.

Compared with the X7 and 5Y series, the MA R range focuses on essential moisture analysis functions while retaining flexible drying methods, programmable measurement procedures and comprehensive result documentation. It is intended for laboratories requiring reliable moisture analysis without the advanced workflow management features of higher-end product families.

Key Features and Benefits

Gravimetric moisture analysis

The MA R determines moisture content by continuously recording the sample mass during controlled drying.

The instrument calculates the analytical result from the reduction in sample mass as moisture evaporates during the drying process. Available result formats include:

Moisture content (%M)
Dry mass (%D)
Moisture-to-dry-mass ratio (%R)
Final sample mass (g)

Four programmable drying profiles

The analyzer provides four drying profiles that allow the heating process to be adapted to different sample characteristics.

Standard – conventional drying
Mild – gradual heating for temperature-sensitive materials
Fast – accelerated drying for samples with higher moisture content
Step – three programmable temperature stages

The step profile enables users to define successive drying temperatures and heating times for analytical methods requiring controlled temperature changes during measurement.

Flexible process completion

Four finish modes are available:

Automatic
Manual
Time-defined
User-defined

These options allow the analytical procedure to be adapted according to moisture loss, elapsed time or sample stability.

Backlit LCD display

The MA R uses a clear backlit LCD display for operating the instrument, selecting drying programs and viewing measurement results.

The interface provides direct access to the principal analytical functions while maintaining straightforward operation for routine laboratory work.

Drying program management

The instrument stores up to 100 drying programs, allowing frequently used analytical methods to be recalled without repeatedly entering drying parameters.

This supports consistent testing procedures for routinely analysed materials.

Six integrated databases

The MA R information system includes six databases for managing laboratory information:

Products
Users
Packaging
Customers
Drying programs
Drying process reports

These databases help organise analytical methods and recorded measurement data while simplifying routine operation.

Communication and data transfer

The analyzer provides:

RS232
USB-A
USB-B
Wi-Fi®

Measurement reports and stored data can be transferred to external systems for documentation or further processing.

The MA R also supports GLP/GMP reporting and sample traceability functions.

Heating module options

Depending on the selected model, the analyzer is available with an IR emitter, halogen lamp or metal heater.

The standard maximum drying temperature is 160 °C, allowing the heating method to be selected according to laboratory requirements and established analytical procedures.

Model selection guide

For routine laboratory moisture analysis: the MA R series provides the essential functions required for everyday moisture determination.
For applications requiring higher weighing resolution: select the 50 g or 200 g models with 0.1 mg readability.
For larger sample quantities: choose the 110 g or 210 g capacity versions.
For laboratories using different heating technologies: select the appropriate IR, halogen (WH) or metal heater (NS) configuration.
For laboratories that do not require the advanced ELLIPSIS platform, touchscreen operation or electronic record management available in the 5Y series: the MA R provides a simpler operating environment while retaining programmable drying methods and comprehensive measurement functionality.
