PR-127 BAROMETER SYPHON

Syphon barometers are the simplest of the mercury barometers.

This barometer has a thick-wall glass tube, closed at one end, open and turned upwards and widened to form a small reservoir.

For demonstration, mercury column is feasible.

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.

The scale is graduated in metric and English system.

Zero point adjustment is carried by a screw clamp attached to a glass tube.

The entire set up is fitted on a wooden polished base.

It is supplied without mercury.
