The Testo 510 Manometer is an all in one, low pressure measurement solution. The Testo manometer can measure total external static pressure, differential pressure, duct velocities, manifold pressures, & air flow with pitot tube (optional). The differential pressure measurement is temperature-compensated for exact readings. The readings can be displayed in pascal over the entire measuring range (0-100 hPa). In conjunction with a pitot tube, Testo 510 measures the air velocity in the range of 10 to 100 m/s. With the 510 manometer, performing system tests has never been easier using our single, easy to use, rugged, compact digital manometer. Its small form factor, bright backlit display, & magnetic backing for hands-free work will enable the Testo 510 to be used in a wide variety of applications. The testo manometer 510 is very handy, small and easy to operate.

Unfortunately, the specifications only describe differential and positive pressure measurement.
Well, in the field, you can always zero out your measurements using the up button. Be careful, as this will adjust the testo 510 so that it uses the ambient readings as a baseline.
