Demonstration Analog Manometer, Borosilicate Glass, 22.5"

This large-scale demonstration manometer measures 22.5 inches and is used for measuring and indicating the pressure of liquids and gases. It includes an open-ended U-tube with a side arm mounted onto a support structure for stable classroom display. The analog design provides a clear, visual representation of pressure differences, making it well suited for physics demonstrations and instruction in fluid mechanics and gas laws.
