testo 512 - Pressure and flow velocity measuring instrument 0 to 2 hPa

Order-Nr. 0560 5126

8 measurement units to choose from: psi, kPa, hPa, Pa, mmH₂O, mmHg, inH₂O, inHg
2 air flow units to select from: fpm, m/s
Integrated density compensation
Backlit display / min and max values / hold function

The testo 512 differential pressure meter is available in 4 different models. This model has a measuring range of 0 to 0.80 inH₂O (0 to 2 hPa), and is ideal for measuring pressure differences at filters, and for carrying out pitot static tube measurements in air ducts at air flow speeds between 2 and 17.5 m/s.

Product Description

The testo 512 provides simultaneous pressure and flow measurements in one compact, versatile instrument. It offers two user-switchable units of flow, feet per minute (fpm) and meters per second (m/s). Eight different units of pressure can be selected: psi, inH₂O, inHg, kPa, hPa, Pa, mmH₂O, and mmHg. All readings are clearly visible on a large backlit display. The versatile testo 512 provides smoothing between 1 and 20 display refreshes (0.5 sec), yielding a sliding mean reading. Density compensation is built-in. A separate HOLD-MIN-MAX button freezes readings, and displays both flow and pressure extremes. Optional accessories include the testo IR printer for on-site documentation of all measurements by date and time, plus the clear TopSafe for protection against dirt, moisture, and impact.
