Testo 521-3 Low-Range Differential Pressure Instrument (up to 2.5 hPa)

Overview

The Testo 521-3 differential pressure measuring instrument is designed for high-precision low-range differential pressure measurements up to 2.5 hPa in air-conditioning and ventilation technology. Thanks to its high level of accuracy and outstanding resolution, it can be used, for example, for measurements in clean rooms and for flue inspections.

In conjunction with an optional pitot tube, the integrated pressure sensor also measures flow velocities from 1 to 20 m/s. With two external channels and one internal channel, a fast 0.04 s measuring rate and both NTC and TC Type K temperature inputs, the testo 521-3 is a versatile precision instrument for sensitive pressure and flow tasks.
