Alnor Velometer Thermal Anemometers

Understanding low-velocity airflow is central to many R&D efforts, from clean environment design to displacement ventilation and contaminant transport studies. Alnor Velometer thermal anemometers are designed to capture these flows with sensitivity and stability, helping teams quantify velocity fields where other methods may struggle.

Research-ready capabilities:

• Thermal sensing probes detect low speeds, enabling boundary layer and near-field assessments.
• Slim probe geometry reaches diffusers, plenums, and tight spaces often found in prototypes and test rigs.
• Averaging and data logging support stable readings and traceable results for reports and publications.
• Temperature measurement and compensation (model dependent) help refine analyses.

Typical R&D applications:

• Low-flow ventilation mapping for comfort and energy studies.
• Cleanroom and controlled environment airflow characterization.
• Validation of CFD models and air distribution prototypes.
• Source control and contaminant transport research.

Workflow integration:

• Combine with micromanometers for pressure data and pitot-based velocity in higher-speed regions.
• Use capture hoods for volumetric benchmarks at terminals, cross-checking velocity-derived estimates.
• Pair with rotating vanes for face velocity surveys on grilles and exhausts.

Alnor Velometer instruments help researchers move from qualitative observations to quantitative, repeatable measurements across a broad range of test conditions. TSI offers guidance on probe selection, calibration, and data workflows so your team can build a measurement plan that supports peer review, funding milestones, and product development timelines.
