SIPHON BAROMETER

SIPHON BAROMETER:

It is the term sometimes applied to the simplest of mercury barometers. When placed into the upright, “U”, position, mercury will flow away from the sealed end, forming a partial vacuum, until balanced by atmospheric pressure on the other end.

Specifications:

• A low cost, simple barometer yet having sufficient accuracy.
• The whole column of mercury is clearly visible in the glass tube.
• Reservoir has a screw cap at the top, the thread’s gap being sufficient to balance the atmospheric pressure by confining the mercury vapors.
• Complete apparatus mounted on a polished wooden board.
• Supplied without mercury.
