Today I will be going over the TSI 9515 VelociCalc Air Velocity Meter. This meter is an excellent entry level air velocity meter for the professional HVAC technician. The TSI 9515 separates itself from the plethora of air velocity meters in this price range by having a range of 0 to 4,000 ft/min (0 to 20 m/s) and an accuracy of 5%. Included is a straight probe, which makes this unit perfect for any face velocity measurement.  The TSI 9515 VelociCalc Air Velocity Meter has a large easy to read display and has an easy to navigate menu. The 9515 can also measure temperatures from 0 to 200 Degrees Fahrenheit and has an accuracy of 0.5 Degrees Fahrenheit. If you are in the market for a new meter, I would suggest checking this out.

Cheers and Happy Testing,
