TSI AP500 AirPro Air Velocity Meter

  • Bluetooth communication with iPhone and Android devices
  • Stackable probe extensions
  • High-accuracy measurements
  • Rechargeable battery
  • Easy to change probes (not included, see below to choose)


The TSI AP500 AirPro Air Velocity Meter makes highly accurate air velocity, temperature, and relative humidity measurements, with options to send readings to a connected smartphone or tablet via Bluetooth. Probes are easily installed and swapped according to which parameters need to be measured. And when probes must reach out-of-the-way places, extensions are easily added to increase length, while minimizing overall diameter. The TSI AP500 interface is simple enough to navigate with one hand, and the high contrast display can be seen even in bright sunlight. The included rechargeable battery will keep going as long as you do, providing 8 hours of measurements.

The TSI AirPro app extends the functionality of the AP500 with communication to both Android and Apple iOS devices. The app comes with 3 access levels: free, advanced, and professional. Included in the free version is the ability to view multiple parameters from the meter at once and display the measurements with either metric or imperial units. An advanced-level subscription allows the app to calculate volumetric air flow, web-bulb and dry-bulb temperatures with select probes, generate reports, record statistics (min/max/average), and display and log data from two meters at once. Stepping up to the professional-level subscription adds duct-traversing, graphing, and SD card utilization capabilities for long-term data recording, as well as the ability to connect to 6 meters at the same time.
