The differential pressure gauge testo 510i, in combination with a smartphone or tablet, is suitable for measurements of gas flow and static pressure, pressure drops on ventilators and filters, and for pressure-drop tests on gas pipes. It can also be used for determining air flow velocity and volume flow. Via the testo Smart Probes App installed on the end device, users can comfortably read off their measurement values, configure volume flow measurements quickly and easily, and reliably determine timed and multi-point mean values. The App also includes a measurement menu for the pressure-drop test including alarm. All measurement data can be presented either as a diagram or in tabular form. The measurement protocols can then be sent directly as PDF or Excel files.

Use this manometer from Testo to measure both the air flow velocity and the volume flow of a fluid. It's also suitable for measuring gas flow, static pressure, pressure drops on ventilators and pressure-drop tests on gas pipes. The device connects to Testo's Smart Probes App on your smartphone for ease of use. The manometer sends the data to the app, which presents it as a diagram or a table. You can then use the app to convert the data to a PDF or Excel file for simple organisation and interpretation of data.
