TSI

TSI makes instruments for airflow, indoor air quality and particle measurement, and its Alnor products are widely used in HVAC balancing. TSA lists Alnor capture hoods, micromanometers, thermo-anemometer probes, duct leakage testers and Q-Trak air quality meters. Compare range, probes and logging for your testing and balancing tasks, and check that hoods, stands and probes match the instrument model.
