The testo 510 digital manomenter is an all in one, low pressure measurement solution.  The 510 can measure total external static pressure, differential pressure, duct velocities, manifold pressures, and air flow with pitot tube (optional).

Features:

• Temperature and air density compensation for accurate airflow measurements
• Measures differential pressure to 40 in. H₂O
• Backlit display ensures easy readability in low light situations
• Temperature compensated pressure sensor
