Alnor

Alnor ventilation instruments are engineered to help research teams quantify airflow behavior, characterize system performance, and document findings with confidence. Whether you are benchmarking diffuser performance, validating variable air volume strategies, or modeling low-flow ventilation, Alnor offers a complete toolkit for high-quality measurements in both controlled and real-world environments.

Purpose-built for R&D, Alnor devices balance robust hardware with intuitive operation so teams can spend more time on insight and less on setup. Capture hoods measure volumetric flow at diffusers and grilles. Micromanometers deliver finely resolved differential pressure readings for pitot traverses and static pressure checks. Rotating vane and thermal anemometers capture velocity — from face measurements to ultra-low flows — supporting studies that range from ventilation effectiveness to energy optimization.

What sets Alnor instruments apart for research teams:

• Measurement fidelity: High-resolution sensors and stable electronics support consistent readings across trials.
• Application flexibility: Interchangeable hoods, probe options, and accessories adapt to evolving test plans.
• Data-centric workflows: Logging and export functions help integrate results into analysis pipelines and lab reports.
• Portability and durability: Lightweight, rugged designs help researchers collect data in labs, mockups, and occupied spaces.
• Calibration support: Factory calibration services help keep instruments aligned with quality and QA/QC requirements.

Typical R&D applications include:

• Air distribution research, including diffuser characterization and supply/return balance studies.
• Low-flow ventilation experiments and cleanroom airflow mapping.
• Validation of control strategies, such as demand-controlled and displacement ventilation.
• Duct and plenum investigations, including pressure loss and fan curve assessments.
• Indoor environmental quality (IEQ) studies where airflow interacts with temperature, humidity, or contaminants.

Alnor instruments are designed to support global test standards and internal SOPs, helping teams align methods with stakeholder expectations. Paired with sound experimental design, they can help reduce uncertainty, improve reproducibility, and accelerate time-to-insight.
