testo 510 - Differential Pressure Meter

• Measurement Range: Measures differential pressure from $0\text{ to }100\text{ hPa}$ ($0\text{ to }40.15\text{ inH}_2\text{O}$) with a high accuracy of $\pm0.03\text{ hPa}$ at low ranges.

• Flow & Velocity Capable: Calculates air velocity ($\text{m/s}$ or $\text{fpm}$) and volume flow when paired with an optional Pitot tube.

• Environmental Compensation: Built-in temperature and air density compensation ensure reliable readings across varying conditions.

• Multi-Unit Selection: Supports 10 selectable pressure units ($\text{hPa, mbar, Pa, mmH}_2\text{O, mmHg, inH}_2\text{O, inHg, psi, m/s, fpm}$).

• Field-Ready Design: Features a backlit display, rear-mounted magnets for hands-free attachment to ductwork, and an IP40 protective casing.
