Model  Description 
0560 0526  512 Digital Manometer / Anemometer +/- 1" WC (0 to 2hPa)
0560 0527  512 Digital Manometer / Anemometer +/- 10" WC (0 to 20hPa)
0560 0528  512 Digital Manometer +/- 80" WC (0 to 200hPa)
0560 0529  512 Digital Manometer +/- 30psi (0 to 2000hPa)

testo 512 shows pressure and flow simultaneously in an easy-to-read, large, backlit display.
Measurement data is printed on site with date and time as well as minimum and maximum values.
testo 512 has two switchable units for flow: m/s and fpm.
The displayed actual value can be frozen in the display by pressing the HOLD button.
The measured minimum and maximum value can be displayed and stored in the meter.
TopSafe protects the meter in the field from impact, dirt and splash water.

Applications:
Simultaneous measurement of pressure and velocity using a Pitot tube on air
conditioning/ventilation units.
Measures the pressure in the central locking system of vehicles.
Monitors differential pressure in filters (within air conditioning and ventilation systems).
Measures differential pressure for clean room monitoring.
Measures positive and negative pressure in air conditioning ducts.
