TSI VelociCalc 8345 Portable Air Velocity Meter for HVAC and IAQ Measurements

The TSI VelociCalc 8345 is a handheld portable air velocity meter specifically designed for precise measurement of airflow velocity and temperature in HVAC and indoor air quality (IAQ) applications. It calculates airflow flowrate by incorporating user input on duct size and shape, supporting duct traverse measurements commonly required in ventilation system testing and bioprocessing environments.

Key technical features include:

• Extended velocity measurement range from 0 to 6,000 ft/min, suitable for a wide variety of airflow conditions encountered in biomedical engineering and cleanroom airflow studies.
• Temperature measurement capability from 0 to 140°F (approx. 0 to 60°C), critical for evaluating environmental conditions affecting molecular diagnostics and biomanufacturing air quality.
• Multi-value averaging to provide stable readings over time, with minimum and maximum velocity tracking, enhancing accuracy in fluctuating airflows during controlled bioprocessing processes.
• Variable time constant modes ensure steady display output, essential for capturing reliable data where airflow varies rapidly in synthetic biology laboratory setups.
• Telescoping probes with etched length markings facilitate precise and repeatable duct traverse measurements, a vital feature in airflow characterization needed for tissue engineering cleanroom environments.
• Sampling function allows for efficient recording of multiple measurement points, supporting detailed airflow mapping and compliance with indoor air quality standards relevant to molecular biology workflows.

This air velocity meter is widely adopted in HVAC performance evaluations, environmental monitoring, and biotechnological applications requiring accurate airflow and temperature profiling essential for ensuring sterile and stable laboratory conditions. The TSI VelociCalc 8345 supports critical bioprocessing tasks and molecular diagnostics by providing robust and reliable airflow measurement data integral to quality control and system validation protocols.
