For many laboratory and field studies precise knowledge of the vacuum or pressure is essential. Use of traditional mercury manometers for such studies is often no longer allowed, while use of water manometers is inconvenient for most laboratory and field applications.

The digital manometer shown is a handy, low cost meter to measure vacuum and pressure in the field and in the laboratory. The meter can be set to measure pressure and vacuum in 11 modes, from mm Hg to mbar or cm H2O.
