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
