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. Click here for datasheet Key Features: Measures air velocity, volume flow, and temperature as well as air flow at registers and 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 Overview 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 severalinstruments. 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 timeconsuming paperwork!
