Testo 510i Differential Pressure Measuring Instrument (Smart Probe)

Overview

The Testo 510i differential pressure measuring instrument, used in conjunction with a smartphone or tablet, is ideal for quick and easy measurement of gas flow pressure and static pressure, as well as pressure drops on fans and filters. As part of the testo Smart Probes range, it keeps measurement simple and cable-free.

Operated via the free testo Smart App over Bluetooth®, the 510i displays readings on your mobile device, where they can be documented and shared. Used together with a pitot tube it also determines air velocity and volume flow, making it a versatile pocket tool for HVAC service, commissioning and gas-pressure work — for example, a rooftop technician checking filter ΔP and logging pitot airflow without a separate cable-bound manometer.

Who it is for: Choose the 510i when you want a pocket Bluetooth ΔP probe with app reports (PDF/Excel), timed and multi-point means, and a pressure-drop test menu with alerts. Prefer a handheld with its own display and wider fixed ranges? Compare the Testo 512-1 and our 512-1 vs 512-2 guide.

FAQ

Does the Testo 510i need a smartphone?
Yes. Readings, configuration and reports run through the free testo Smart App over Bluetooth® (typical requirements: recent iOS/Android with Bluetooth 4.x).

Is a pitot tube included?
No. Pitot tubes are optional accessories for air velocity and volume flow; the hose set for ΔP is included.

How does 510i compare with Testo 512?
510i is a cable-free Smart Probe for phone/tablet display and app documentation. 512-series instruments have an on-board display and fixed ΔP ranges suited to stand-alone HVAC balancing.
