These Smart Probes are designed to be used with smartphones and tablets. Users can read the measurements using the testo Smart Probes App installed on their smart device. The App allows you to remotely read measurements from up to six Smart Probes and easily document/report the results. 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. The app works on smart devices with either Android or Apple operating systems (requires iOS 8.3 or newer; requires Android 4.3 or newer; requires mobile end device with Bluetooth 4.0.).

testo 405i - Hot-wire anemometer:
Wireless instrument for measuring air flow velocity, temperature, and volume flow
Measures in-duct air flow and automatically calculates volume flow (enter duct dimensions simply)
Small diameter (<0,5") and 15" telescopic shaft length is ideal for in-duct flow averaging and timed traverse
Perform air duct leakage tests

testo 410i - Vane anemometer:
Wireless instrument for measuring air velocity, volume flow, and temperature as well as air flow at registers
Automatically calculates volume flow (enter duct dimensions simply)
No air density correction required due to design
Measure volume flow at several outlets simultaneously (using mutiple Smart Probes) to adjust system balance
Timed/multipoint averaging to get accurate air flow profiles

testo VAC kit:
testo Smart Probes VAC kit for servicing on ventilation and air conditioning systems. For the measurement of air and surface temperature, humidity, air velocity and volume flow.
