High-flow resistance meter
Ideal for measuring the airflow resistivity of highly resistive materials such as aeronautical liners, resistive films, and perforated plates.
Description
Mecanum’s high-flow resistance meter measures airflow resistivity, resistance, normalized resistance, and permeability of porous and highly resistive materials, including aeronautical liners, resistive films, and perforated plates. Where a standard resistivity meter works at low flow velocities, The high flow resistance meter extends the range to the high flows these resistive materials require. It is built for speed as much as accuracy: ready in under a minute, with measurement and results in under ten, through a clear, guided interface that keeps operator workload low.

Software
SIGMA HD-X
Through an intuitive single-window interface, SIGMA HD-X ensures precision and repeatability across your high-flow resistivity campaigns. The measurement is fully automated, with seamless auto-ranging that adapts to the material’s resistance to maximize precision, and it stays clear enough for new users to run reliably. Advanced tools take you further, averaging, evaluating penetration depth, comparing projects, and selecting a custom flow speed, and a one-click Excel report documents everything professionally.
