The device consists of an U-tube of 48 cm height (channel’s diameter is (3.5-4.5) cm) and a stand. The stand is labeled with scale marks. A glass T-joint is fixed behind the top of stand. The T-joint connects manometer, the whole device and appendix with rubber nipple. The nipple holds a clamping screw or a paddy clip. Thus, the manometer could be calibrated without disconnecting other devices. Rubber nipple and clamping screw are included.
