Testo 521-2 - Differential Pressure Instrument 0 to 100 hPa (±0.1% of f.v.) (Part Number 0560 5211)

Integrated differential pressure sensor with an accuracy of 0.1% of f.v.
Calculation of flow velocity and volume flow via pitot tube (optional)
Multi-point and timed mean calculation
2 probe inputs for additional pressure and temperature probe
PROBES SOLD SEPARATELY - click here for probe list

The testo 521 series are highly accurate differential pressure measuring instruments with an internal sensor. The testo 521-1 and testo 521-2 both have a measuring range from 0 to 100 hPa, however they are available in two accuracy classes:

testo 521-1: accuracy 0.2 % of final value
testo 521-2: accuracy 0.1 % of final value

The 521-1 and 521-2 are optimally suited to checks on extraction systems and ventilators, as well as the monitoring of pressure drop at filters. In combination with a Pitot tube, the internal sensor measures flow velocities from 5 to 100 m/s. The instrument additionally has two probe inputs for the connection of further probes for the measurement of pressure and temperature. A large selection of probes is available for this purpose.

The testo 521-3 has a measuring range of 0 to 2.5 hPa and records even the smallest pressure differences without difficulty. Its high accuracy and a resolution of 0.1 Pa make it ideal for differential pressure measurements in cleanrooms. In combination with the Pitot tube, the internal sensor measures flow velocities from 1 to 20 m/s. The testo 521-3 is also equipped with two probe inputs for the connection of further probes for the measurement of pressure and temperature.

I have this question too (0)

These devices are similar, however, they cover different pressure ranges and accuracy levels. • 521-1 ? 0 to 100 hPa ? (±0.2% of f.v.) • 521-2 ? 0 to 100 hPa ? (±0.1% of f.v.) • 521-3 ? 0 to 2.5 hPa ? ±0.5 Pa (0 to 20 Pa) ? ±(0.5 Pa ±0.5 % of mv) (20.1 to 250 Pa)
