Precision Moisture Analysis: The Invisible Critical Factor in Aerospace and Drone R&D

In high-performance engineering things like aerodynamics, structural strength and weight savings are high on the important list. For the engineers at the cutting edge of Aerospace, Motorsport, and Drone development, the highest variance in strength and weight is often what you cannot see, moisture.

At scalesandbalances.co.uk, as part of the Brash Group, the UK’s largest privately owned weighing service provider, we have seen how the precise measurement of moisture content separate industry leaders from the rest. While many focus on the final “take-off weight,” the real technical edge starts at the material level.

The Problem: Hygroscopic Failure in Composites and Polymers

Advanced materials like carbon fiber pre-pregs and high-performance 3D printing filaments (PEEK, Ultem, and Nylon) are hygroscopic. They do not just sit there; they actively breathe in moisture from the workshop floor.

• Delamination Risk: In an autoclave, trapped moisture in composite layers turns to steam, creating internal voids that compromise structural integrity.
• Additive Manufacturing Defects: Moisture causes hydrolysis during the 3D printing melt phase, leading to brittle parts and surface pitting.
• The Weight Penalty: In a sector where every gram is scrutinized, absorbed water is “dead weight” that offers zero structural benefit.

The Solution: Why the A&D MS-70 is the Industry Hidden Gem

The Precision Gap: Why General Moisture Analysers Fail

Most moisture analysers on the market are designed for food or general industrial use, where moisture levels are measured in whole percentages. They lack the resolution required for the ultra-low moisture levels found in aerospace-grade plastics, resins, and filaments.

For these applications, there is realistically only one choice that balances surgical precision with commercial sense: the A&D MS-70 Moisture Analyser.

Why the MS-70 is the Aerospace Standard:

• 0.0001g (0.001%) Resolution: The MS-70 can detect moisture levels that are invisible to standard industrial scales, providing the “pass/fail” data needed for critical composite cures.

• Secondary Radiation Heating: Unlike standard halogen lamps, the MS-70 uses a SRA (Secondary Radiation Assist) filter to heat the sample uniformly, preventing the “surface scorching” that can ruin technical resin samples.

• Data Traceability: With WinCT-Moisture software, engineers can plot real-time drying curves—essential for proving process control during aerospace audits.

Why Partner with a UK Leader?

As one of the UK’s largest authorized dealers for A&D equipment, we do not just ship boxes. Our authority is backed by the nationwide reach of the Brash Group.

• In-House and On-Site Calibration: Our dedicated service engineers and in-house operatives provide UK-wide calibration and re-calibration for A&D moisture balances like the MS-70 and all major brands such as Ohaus, Kern, Adam and more.
• Technical Sovereignty: We ensure your equipment remains traceable and compliant with the stringent quality standards required in Aerospace and Motorsport.
• The Brash Group Edge: Being part of the UK’s largest privately owned weighing service company means we have the technical depth to support your R&D lab from initial setup to annual certification.

Another top tip: In a non-food environment like this moisture analysers are typically used for internal process verification and R&D, a standard traceable calibration is often sufficient. While UKAS-level conformity is available, many laboratories find that our standard high-precision calibration provides the necessary data integrity without the additional ‘audit-heavy’ costs associated with other weighing categories.

Integrating Precision into Your Workflow

If your team is pushing the boundaries of Scales for Aerospace or Scales for Drones, do not let moisture be your undoing.

Precision starts with the raw material. By utilizing the A&D MS-70, you ensure your material science is as rigorous as your flight physics.
