Manometer Testo model 521-1

MONOMETER TESTO 

MODEL 521-1

The high-precision differential manometer text 521-1 is the ideal solution to accurately measure the differential pressure in the field of ventilation and air conditioning systems, eg. to locate pressure losses in the filters, to control the suction fans and plants, or for carrying out the traditional measures with Pitot tube.

Advantages:

integrated sensor for differential pressure (temp. compensated)
direct calculation of air velocity and flow
the average over time and points calculation
2 additional inputs for external probes of temperature and pressure
The text 521-1 differential pressure gauge has been developed to accurately measure the differential pressure in the field of ventilation and air conditioning systems. The instrument is particularly suited to locate pressure losses in the filters, to analyze the suction fans and installations. Or for carrying out the traditional speed and flow measurements with a Pitot tube in the ventilation duct or the air in the process (in the range from 5 to 100 m / s).
The differential pressure gauge has a temperature-compensated differential pressure sensor integrated which has an accuracy of 0.2% FS is also possible to connect up to 2 optional probes, and transform the differential pressure gauge in an all-round talent tailored to your needs. Wide range of probes, including:

• Differential pressure probes
• Probes for absolute pressure
• Probes for relative pressure
• Temperature probes (eg. Superficial probes or immersion / penetration probes)
Technical characteristics of the text 521-1 differential pressure gauge
Thanks to the integrated sensor for differential pressure, the measuring 521-1 text tool is able to calculate the flow velocity and the volumetric flow through a Pitot tube (available separately). The differential pressure gauge also offers a convenient feature for calculating the average over time and points.
Possible also long term monitoring: in this case the data are saved individually or in the form of series of measures. The user can select the measurement frequency and the number of values to be saved. The dynamic measurements can be stored in the measuring instrument with a 0.04-second cycle.
With the help of the optional ComSoft software, you can play online measurement via the PC, save the data according to the measuring point, and analyze them to the PC. To print the measured values directly on site is also available quick text printer.
To measure the pressure you can choose from the following units: mbar, hPa, bar, Pa, kPa, inH2O, mmH2O, torr and psi. With the push of a button the average value are displayed, the last measured values as well as min / max values.
