Testo 521-2 Differential Pressure Measuring Instrument

Introduction of Testo 521-2

The Testo 521-2 differential pressure measuring instrument is designed for precise differential pressure measurements in air conditioning and ventilation systems. It excels at measuring pressure drops on filters and checking fans and extractors. Additionally, it is suitable for Pitot tube measurements in ventilation ducts or process air, within the 5 to 100 m/s range.

The differential pressure measuring instrument features an integrated temperature-compensated differential pressure sensor with an accuracy of 0.1% of the final value. Additionally, it allows for the attachment of up to two optional probes for expanded measurement capabilities.

Testo 521-2 Key Features

• Integrated differential pressure sensor with an accuracy of 0.1 % of f.v.
• Calculation of the flow velocity and the volume flow via Pitot tube (optional)
• Multi-point and timed mean calculation
• 2 probe inputs for additional pressure and temperature probes
