TSI¡¯s VelociCalc¢çPlus Meters simultaneously measure and data log several ventilation parameters
TSI¡¯s VelociCalc¢ç Plus Meters simultaneously measure and data log several ventilation parameters using a single probe with multiple sensors. Based on the model, these hand-held instruments measure velocity, temperature, differential pressure and humidity. All versions calculate volumetric flowrate. The Model 8386 also performs dew point, wet bulb temperature and heat flow calculations.
Features
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)
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
Data Logging Capabilities
Data logging ability allows user to log 1394 samples with a time and date stamp
Simultaneously records all parameters available in each model
Single point and continuous data logging modes to fit your application
Data can be reviewed on-screen, printed or downloaded to a computer spreadsheet program
TSI downloading software permits easy transfer of data to a computer
Statistics function displays average, maximum and minimum values, and the number of recorded samples
