Manometer, Glass
Manometer, Glass (Product Code: SLE/PHY/111) is a liquid-column pressure gauge used to measure small gas pressure differences in physics and chemistry laboratory experiments. Students read the liquid levels against its 80-0-80 centre-zero scale, and the glass tube has a built-in stopcock and is mounted on a 400 x 80 mm backing plate. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Glass Manometer Used For?
Connect one side of the manometer to the system under test with rubber tubing and leave the other open to the air; the difference in liquid level then shows the gauge pressure. Typical school uses include checking laboratory gas supply pressure, showing how pressure increases with depth using a thistle funnel covered with a thin membrane, and measuring the small pressure changes in gas-law demonstrations — core physics lab equipment for schools in India.
Fill it with coloured water to about the zero mark so both levels are easy to read. Because the scale runs 80-0-80, read how far the liquid has fallen on one side and risen on the other, then add the two values for the total level difference. The built-in stopcock lets you isolate the line between readings, and the connector, tapering from 5 mm to 7 mm, holds tubing securely.
What to Specify When Ordering
- Number of manometers needed for your laboratory.
- Rubber tubing to suit the 5–7 mm tapered connector.
- Whether a dye for colouring the manometer water should be included.
OEM Manufacturer
ScienceLab (Jain Scientific Equipments Private Limited) is the original equipment manufacturer of the Manometer, Glass, making and assembling it at its own licensed factory in Saha, Ambala, Haryana, India. Buyers deal with the manufacturer rather than a trading house, so questions about the scale, the stopcock or a replacement tube can be raised directly — ask us. Read our company profile for more.

Frequently Asked Questions
What scale does the Manometer, Glass have?
The Manometer, Glass has an 80-0-80 scale with 2 mm subdivisions. The centre zero lets students read the rise and fall of liquid on either side and add them to find the total difference in level for the pressure being measured.
What size is the manometer?
The Manometer, Glass is mounted on a backing plate of 400 x 80 mm. Its tube measures approximately 406 mm long with a 5 mm diameter, and the retaining ring is 9.5 mm, which keeps the unit compact on a laboratory bench.
What tubing fits the manometer connection?
The connector on the Manometer, Glass has an external diameter of 5 mm, increasing to 7 mm at the end near the retaining ring. Flexible laboratory tubing with a bore to suit this taper will push on and hold securely.
What liquid should be used in the manometer?
Water tinted with a little food colouring is the usual choice for the Manometer, Glass in school experiments because it is safe and easy to read. The liquid is not specified in the listing, so ask us if your practical calls for a different fluid.
Who manufactures the Manometer, Glass?
The Manometer, Glass is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. It is supplied direct from the manufacturer to schools, colleges, laboratories, dealers and importers.
Is a calibration certificate available?
The Manometer, Glass is a teaching instrument with an 80-0-80 scale. If your institution requires a calibration certificate or other documentation, please discuss it with us through the contact page before ordering so we can confirm what can be provided.
