The Testo 405i smart probe thermal anemometer is an air velocity measuring device that links to smart phones and tablet devices to display and log measurement data. The product is suitable for measuring flow rates at grilles / diffusers and the smart probe App calculates the air volume. The probe comes complete with a telescopic shaft that is extendable up to 400 mm.
The Testo smart probes can be used individually or combined with other smart probes to create measuring solutions for most HVAC / HVAR applications.
The Testo 405i works on smart devices with either Android or Apple operating systems. The App is a powerful and easy-to-use tool that allows you to remotely read measurements from up to six (6) smart devices. 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.
