TSI VelociCalc 8386 Multi-Parameter Ventilation Meter
Talk about feature packed -- this little instrument is jammed. The VelociCalc Plus simultaneously measures and logs velocity, temperature, static pressure, Pitot tube readings and humidity, and calculates volumetric flow rate, dew point, wet bulb temperature and heat flow. Multiple sensors but one easy-to-use forty-inch telescoping probe. The rental unit comes with custom software.
Features:
Wide velocity range of 0 to 10000 ft/min
Flowrate feature makes simple calculations of volumetric flowrate when the user inputs the duct shape and size K factor or horn size
Velocity measurements are made from the thermal sensor or a Pitot tube
Automatic conversion between actual and standard velocity readings
Direct calculation of dew point and wet bulb temperature - no psychrometric chart needed (Model 8386 only)
Heat flow function calculates heat transferred after a heating or cooling element (Model 8386 only)
Stable digital display when measuring fluctuating flows
Back-lit display is easy to read in poor lighting conditions
40 inch telescoping probe with etched length marks to make duct traverse measurements easier
Optional articulating probe available
Optional portable printer provides hard copy documentation of your measurements
