Custom Measuring Instruments
Standard instruments don’t always fit the job. That’s why at Mecanum, we specialize in designing and building custom acoustic measuring instruments tailored to your exact requirements.
Whether you need a modified airflow resistivity meter, a non-standard impedance tube, or a completely new system for a specific testing protocol, we work closely with you to create solutions that match your materials, your methods, and your industry standards.
We combine engineering expertise with hands-on collaboration to turn your testing challenges into reliable, accurate, and practical instruments.
High-Flow Resistivity Meter for Snow Testing
Designed For Snow And Ice Testing
When extreme environments demand exact results, Mecanum delivers. This fully customized high-flow resistivity meter was engineered specifically for testing snow samples in cold climate conditions, including operation inside commercial freezers and environmental test chambers.
Perfect for snow mechanics, environmental research, and cryogenic studies, this Mecanum custom instrument is designed to push the boundaries of what’s possible in low-temperature testing.
Certified for cold room use at -10°C
With electronics certified for continuous use at -10°C, this system ensures dependable performance where standard equipment would fail. A wide-range mass flow controller allows for accurate measurement across varying resistivity levels — even in high-resistance snow and ice materials.
Transparent sample holder for real-time visual inspection
A transparent, thermally insulated sample holder gives users real-time visual access to the specimen, without compromising thermal control or test accuracy.
Airflow Resistivity Meter for Wet Sample Testing
Designed For moisture-heavy materials
When moisture becomes a challenge, Mecanum has the solution. This custom airflow resistivity meter is tailored to meet ASTM C522 standards for wet and water-saturated materials, delivering accurate, repeatable results where off-the-shelf instruments fall short.
Ideal for insulation testing, bio-based composites, and porous materials that retain water, this custom system helps you stay compliant — and confident — no matter how wet the sample.
Smart sample holder design to manage water runoff
The specially designed sample holder not only accommodates wet materials but also protects electronics from exposure, directing excess water away from critical components to keep your lab dry and your data reliable.
High-Level Impedance Tube for Curved Surface Testing
Designed for curved and contoured surfaces
For applications where surface geometry complicates the test, this custom impedance tube from Mecanum brings unmatched precision. Developed to evaluate aeronautic nacelle liners and other curved acoustic materials, the system conforms perfectly to complex shapes — ensuring reliable data and consistent measurements.
From aerospace labs to OEMs, this high-level solution ensures full ASTM E1050 & ISO 10534-2 compliance and next-level accuracy in every test.
Curved tube interface for perfect sample contact
Its curved interface eliminates edge gaps and alignment issues that compromise accuracy, while our proprietary microphone positioning tool maintains exact spacing for precise phase correction — meeting the highest standards in acoustic testing.
Custom-diameter and large-format impedance tubes
When standard impedance tubes don’t fit your materials or testing goals, Mecanum builds the one that does. We create custom-diameter and large-format acoustic tubes to meet your exact requirements, including unique sample holders, coupling systems, and test configurations.
Recent custom builds include:
• A 58 mm tube with a square-to-round sample adapter
• A 1 ft × 1 ft low-frequency tube for large-format testing
• A reduced-section insert for earplug and small component testing
We design around your materials — circular, square, or custom geometry — and integrate options like mass flow controllers for high-resistivity samples when needed.
