The testo 510i Smart Probe is a wireless differential pressure probe used for accurate low-pressure measurements. The testo 510i is great for measuring pressure in manifolds, static pressure, and pressure drops in buildings or ventilation systems. Use it to measure the pressure drop across coils and filters or in ducts and systems. Users can read the measurements using the testo Smart Probes App installed on their smart device. It can be used for determining air velocity and volume flow when used with Pitot tubes (not included). The testo 510i 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!
