Small, handy and practical: the testo 511 absolute pressure meter measures absolute pressure and is also suitable for measuring the barometric altitude between two points.

The high-precision testo 521-1 differential pressure measuring instrument is ideal for accurate differential pressure measurements in air conditioning and ventilation technology, for instance for pressure drop on filters, checking fans and extractors or for Pitot tube measurements.
