testo 521-1 Differential Pressure Meter, 0... 100 hPa / -0.2 percent fsv, including battery and factory report.

Product Introduction:

testo 521-1 High precision pressure gauge with built-in pressure sensor 0 to 100 hPa Suitable for measuring flow rates 0 to 100 m/s with pitot tube.testo 521-1 has 2 accuracy grades.testo 521-1 has a built-in pressure sensor rated 0.2percent. The external 100 Pa probe can measure the wind speed range of 1 ~ 12 m/s. Measurement data are stored directly in the instrument and analyzed by computer, or printed on site by testo printer

Advantages at a glance:

• Differential pressure probe has temperature compensation

• 2 probe jacks for connecting pressure and temperature probes

• Direct calculation of wind speed and volume

• Multi-point mean and time mean calculation

• Air density compensation

• Two 4 to 20 mA output jacks are used to connect instruments for signal output of host measurement parameters

• The testo 521 can also supply power to transmitters, such as 4 to 20 mA sockets that can be connected to testo 521,526,400,650, and 950 handheld instruments

• 2 custom probes allow connection of external probes for pressure, temperature, current/voltage, etc
