Users can read the measurements using the testo Smart app installed on their smart device. The app lets users configure duct dimensions to calculate volume flow measurements. Use the testo 405i along with the testo 605i thermo-hygrometer to determine cooling and heating performance. The testo 405i works on smart devices with either Android or Apple operating systems.
The testo Smart 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 and 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!
