Manometer Open U-tube with Nakamura-type Water Pressure Apparatus
Product Code : JL-LEP-10210
The Manometer Open U-tube with Nakamura-type Water Pressure Apparatus (SKU JL-LEP-10210) measures the pressure difference of fluids. The glass U-tube manometer has a 50 cm arm and a millimetre scale on a wooden board and stand, and it connects by 1 metre of silicone-rubber tubing to a Nakamura-type water pressure apparatus whose body rotates around a rigid L-bent tube. Students lower and turn the probe in water and read the pressure change. JaincoLab supplies it as per DepEd guidelines.
Specifications
The set is specified by its manometer tube, scale, mounting, pressure apparatus and tubing: an open glass U-tube with 50 cm arm, funnel top and ribbed tip, 1 mm wall and 4-6 mm bore, a mm scale, a wooden board and stand, a rotating Nakamura-type unit with 10 spare diaphragms and 1 m of tubing.

Applications of the U-tube manometer
The set is used in lessons on pressure in liquids, where students measure how pressure changes with depth and direction. Typical uses are:
- Showing that liquid pressure increases with depth
- Showing that pressure at one depth acts equally in all directions by rotating the probe
- Reading pressure differences on the millimetre scale
- Comparing pressure in liquids of different density
