The A&D MX-50 Moisture Analyzer measures moisture content using the loss-on-drying method. It weighs a sample, heats it with a halogen lamp and calculates moisture content from the change in mass.
With a 51 g capacity, 0.001 g weighing readability and 0.01% moisture display resolution, the MX-50 is suited to Canadian food processors, ingredient manufacturers, research laboratories and industrial QA/QC teams that need consistent moisture testing.
The MX-50 offers adjustable drying programs, a 50–200°C temperature range, memory for test methods and results, and RS-232C data output for laboratory recordkeeping.
Food and beverage quality control, powders and ingredients, bakery products, pet food, agricultural samples, chemical manufacturing, plastics, university research and industrial moisture testing.

Moisture display resolution and weighing readability are not the same as measurement accuracy. Actual performance depends on sample preparation, test conditions and method suitability.
The MX-50 allows laboratories to control both how a sample is heated and when the measurement finishes.
Measurement modes:
Heating patterns: Standard, Quick, Ramp and Step provide different temperature profiles for suitable samples.
The MX-50 stores up to 20 measurement programs, helping laboratories use consistent settings for products tested regularly.
Method selection matters: A drying temperature that works well for one ingredient may be unsuitable for another. Establish the appropriate settings using your laboratory's reference method and sample requirements.
The manufacturer's instructions also describe an automatic reduction of the maximum drying temperature to 160°C after one hour of operation.
The standard equipment package described by Cambridge includes:
The supplied software format and accessories should be confirmed against the current factory package when ordering.
The MX-50 has three different types of performance checks to consider:
These are different procedures. A moisture reference sample does not replace temperature or weighing calibration.
For laboratories with formal quality systems, confirm which procedures, calibration frequencies and documentation are required by your internal quality program.
The MX-50 includes an RS-232C interface and supports A&D WinCT-Moisture software for data transfer and analysis.
The instrument can store up to 100 test results and output measurement information for laboratory records. It also supports date, time, identification and calibration-related reporting functions.
Because the instrument uses a conventional serial connection and the original software was supplied on CD-ROM, laboratories using newer Windows computers may require an appropriate USB-to-serial adapter and compatible software.
Contact Cambridge to confirm the current WinCT-Moisture software requirements before purchasing if direct computer integration is essential.
For routine operation and instrument maintenance, Cambridge offers the following A&D products:
Other manufacturer accessories include replacement sample pans, pan handles, halogen lamps, calibration weights and communication adapters. Contact Cambridge if you need help confirming the correct part numbers.
Choose the MX-50 when your laboratory needs 51 g capacity, 0.001 g weighing readability and 0.01% moisture display resolution.
Consider the A&D MS-70 when your testing requires finer weighing readability (0.0001 g), a finer moisture display setting or higher sample capacity.
Both instruments use halogen loss-on-drying technology. Selection should be based on the sample type, testing method, required repeatability and budget.

The MX-50 measures mass loss during controlled heating and calculates moisture content using the loss-on-drying method. Results depend on the sample and selected drying procedure.
The MX-50 has a maximum capacity of 51 g and weighing readability of 0.001 g. Its selectable moisture display resolution is 0.01% or 0.1%.
Yes, for suitable samples. Food processors and ingredient laboratories can use the MX-50 to develop and perform moisture testing procedures for powders, grains, bakery ingredients and other materials. Drying conditions should be validated for each product.
Test time depends on the sample, selected temperature and measurement program. The MX-50 offers Quick, Automatic, Timer and other modes, but there is no single test time that applies to every material.
Regular performance checks are recommended. Weighing calibration uses a suitable mass, temperature calibration uses the optional AX-43, and sodium tartrate dihydrate can be used to check moisture measurement performance.
Yes. The MX-50 supports RS-232C data communication and A&D WinCT-Moisture software. Confirm computer, adapter and software compatibility before purchasing for an integrated laboratory system.
No. Moisture content and water activity are different measurements. The MX-50 measures mass lost during drying. A water activity meter measures the availability of water within a sample.
Yes. The MX-50 can support laboratory teaching, formulation development and research where halogen loss-on-drying is suitable for the material being tested.
