Testo 521-1 Differential Pressure Measuring Instrument

Overview

The Testo 521-1 differential pressure measuring instrument is targeted at precise differential pressure measurements in air-conditioning and ventilation technology. With 0.2% full-scale accuracy, it is excellent for measuring the pressure drop on filters and for checking fans and extractors.

The instrument is also suitable for pitot-tube measurements in ventilation ducts or in process air in the 5 to 100 m/s range. 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 521-1 covers a wide range of demanding pressure and flow measurement tasks.
