Features and Benefits

All Models

• 4-inch diameter rotating vane head provides reliable (weighted average of) velocity readings
• Sweep mode makes it easy to sweep across an area for one overall measurement
• Flow rate feature calculates volumetric flow (when the user inputs the duct shape and size or area)
• NIST* traceable calibration certificate

Model 8321

• Displays temperature and velocity simultaneously
• Vane head swivels 270 degrees so display always faces the operator
• Easy, push button operation

• Sampling function records multiple point measurements
• Statistics function displays average, maximum and minimum values, and the number of recorded samples
• Variable time constant modes available for a steady display when measuring fluctuating flows
• Optional 36-inch telescopic probe with an articulated swivel head
• Optional 1.4-inch diameter rotating vane head
• Optional portable printer provides hard copy documentation of your readings

• Allows user to log 2,849 samples with a time and date stamp
• Single point and continuous modes to fit your application
• Data can be reviewed on-screen, printed and downloaded to a computer spreadsheet program
• TSI downloading software permits easy data transfer to a computer

Applications

• Heating and cooling coil analysis
