The TSI VelociCalc Series 955 is a portable, hand-held, multifunction ventilation test instrument designed to work with a wide variety of application-specific plug-in probes to measure air velocity, temperature, humidity, CO and CO2. Calculations include airflow, heat flow, turbulence, wet bulb and dewpoint temperature. Among the many uses are cleanroom certification; testing and balancing; ventilation evaluations; and IAQ investigations. Up to five measurements can be displayed simultaneously, with manual or continuous data logging and Bluetooth printer capability.
