Differential Manometer Instrument - 

The 0563 0510 from Testo is a digital manometer. It 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). With the 510, performing system tests has never been easier using this single, easy to use, rugged, compact digital manometer. Its small form factor, bright backlit display and magnetic backing will enable the 510 to be used in a wide variety of applications. It has accuracy of ±0.01 InH₂O (0 to 0.12 InH₂O) / ±0.03hPa (0 to 0.30hPa), ±0.02 InH₂O (0.12 to 0.40 InH₂O) / ±0.05hPa (0.31 to 1.00hPa), ±(0.0 InH₂O + 1.5% of mV) (0.40 to 40 InH₂O) / ±(0.1hPa + 1.5 % of mV) (1.01 to 100hPa). The differential pressure measurement is temperature compensated for exact readings. The readings can be displayed in pascal over the entire measuring range. It complies to EC Directive: 2004/108/EEC standard.
