• Measures air velocity, volume flow, and temperature
• No air density correction required due to design
• Measures air flow at registers and automatically calculates volume flow (enter duct dimensions simply)
• Measure volume flow at several outlets simultaneously (using multiple Smart Probes) to adjust system balance
• Timed/multipoint averaging to get accurate air flow profiles
• Measurement data is transmitted to the convenient and powerful testo Smart Probes App in your smart device
• Tough, accurate, and easy-to-use
• For all HVAC/R technicians and contractors

The testo 410i Smart Probe is a compact wireless vane anemometer for measuring air velocity, and temperature and deriving volume flow. It is used at air outlets, and for monitoring the air flow of ventilation systems. Users can read the measurements using the testo Smart Probes App installed on their smart device. It is easy to configure volume flow measurements and to reliably run timed multipoint averaging traverses. It is especially useful for balancing multi-outlet ventilation systems by using several instruments. The testo 410i works on smart devices with either Android or Apple operating systems. The testo Smart Probes App is a powerful and easy-to-use tool. It allows you to remotely read measurements from up to six (6) Smart Probes and easily document/report the results. Automatic calculations make it a snap! All measurement data is displayed as instrument readings, tables, or graphs. The measurements can be quickly saved as PDF or Excel files. The App creates custom reports which can be saved and/or shared by email. All your data can be stored and retrieved saving you hours of time consuming paperwork! Testo Smart Probes: Compact Bluetooth Instruments The compact and wireless Smart Probes can be operated by a smartphone or tablet via the testo Smart Probes app, which also provides complete reports at the push of a button. These durable multi-function probes are perfect for all aspects of the HVAC field. The Smart Probes offer you the following • Comprehensive selection of measuring instruments: smartphone anemometer, iPhone (and Android) hygrometer, smartphone thermometer and lots more • Practical kits for the most important applications in heating, air conditioning, ventilation and refrigeration • Operation and documentation entirely via the testo Smart Probes App
