The U Tube Manometer (Product Code: SCL-636/066) is a U-shaped tube of borosilicate glass that measures pressure by the difference in liquid level between its two limbs. It is used for measuring pressure, vacuum, differential pressure and flow in laboratories and plant settings where a dependable, easy-to-read indication is needed. Chemistry, physics and engineering departments use it both for teaching the principle of pressure measurement and for practical checks on gas lines and apparatus. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

With one limb connected to a gas tap, the rise of liquid in the open limb shows the supply pressure above atmospheric; connected to a hand pump or aspirator, it shows the vacuum being drawn. When the two limbs are joined to points on either side of an orifice plate or venturi, the level difference gives the pressure drop from which flow rate is calculated — a standard exercise in fluid mechanics labs. The pressure difference equals the density of the manometer liquid multiplied by gravitational acceleration and the height difference, so students can relate the reading directly to theory. Like other borosilicate glassware, the tube resists chemical attack and changes in temperature.
Clamp the manometer truly vertical, fill it to roughly the middle of both limbs with the working liquid, and check that the two levels match with both ends open before connecting anything. Join it to the apparatus with rubber tubing, tap the glass gently to release trapped bubbles, and read each level at eye level at the bottom of the meniscus for water-based liquids.
The manometer is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab and operates from Ambala, Haryana, India, supplying laboratory glassware and instruments to educational and technical institutions. See the company profile for more information.

Does the manometer come with a scale?
A scale is not mentioned in our current listing. Contact us to confirm how the unit is supplied and whether a scale or mounting board can be included.
What liquid should be used in it?
The working liquid is not listed as supplied. Coloured water is usual for small pressure differences; denser liquids extend the range. Ask us if you are unsure which suits your application.
Can it measure differential pressure?
Yes. Connect each limb to one of the two points being compared; the level difference shows the pressure difference between them.
What is the length of the limbs and the measuring range?
These dimensions are not stated in the listing, and the range also depends on the liquid used. Please send us your required range for a matching recommendation.
Is a calibration certificate offered?
Discuss your requirement with us through the contact page; availability depends on the order.
Do you supply manometers to colleges and export customers?
Yes. We supply institutions and distributors in India and international markets; include the quantity and delivery location in your enquiry.
