Aneroid Barometer Demonstration Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4821
Jlab Export is a leading Aneroid Barometer Demonstration Manufacturer,and suppliers in India
Aneroid Barometer Demonstration (code EL-SLE-4821) is a demonstration-type aneroid barometer used for teaching atmospheric pressure in science laboratories. It is housed in a clear synthetic case that is sealed and airtight all round, and a pressure bulb is provided so the teacher can raise the pressure inside the case and let the class watch the pointer respond. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Aneroid Barometers?
| Model | Purpose | Case | Other listed details |
|---|---|---|---|
| This barometer (EL-SLE-4821) | Classroom demonstration | Clear synthetic case, sealed and airtight | Pressure bulb provided |
| Barometer Demonstration Aneroid | Classroom demonstration | Transparent acrylic case giving a full view of the movement | Supplied with a rubber bellow that increases the pressure when squeezed |
| Aneroid Barometer | Reading air pressure | Bezel and cover glass on a plastic base | 100 mm dial, 28–31 inHg and 960–1060 mbar |
| Barometer Aneroid Wall Mounting | Reading air pressure on a wall | Plastic case, 150 mm diameter | 100 mm dial in inches and millibars |
Pick a demonstration model when the aim is to show how the instrument works; pick the dial or wall-mounting barometer when students need to take daily pressure readings. The two demonstration listings describe a similar set-up, so ask JLab if your choice depends on a detail neither listing gives.
What Is the Demonstration Aneroid Barometer Used For?
An ordinary barometer changes too slowly for a lesson. In this model the case is sealed, so squeezing the pressure bulb raises the air pressure around the aneroid capsule; the capsule is pressed in and the lever system swings the pointer to a higher reading, and when the bulb is released the pointer returns. Through the clear case students can follow how a small movement of the capsule becomes a large movement of the pointer. It supports lessons on air pressure in middle-school science, pressure in fluids in class 11 physics and the weather instruments covered in class 11 geography practical work. Squeeze the bulb gently, keep the instrument away from heat and direct sun, and wipe the case with a soft dry cloth.
What to Specify When Ordering
- Model — this demonstration barometer, the other demonstration listing with a rubber bellow, or a dial barometer for routine readings.
- Dial and scale — this listing does not give them, so state any scale or unit your syllabus or tender requires.
- Quantity — the minimum order is 10 units; add any other weather instruments to the same enquiry.
Frequently Asked Questions
How does the demonstration barometer show a change in pressure?
Squeezing the pressure bulb raises the air pressure inside the sealed case, and the pointer moves as the aneroid capsule is compressed. Releasing the bulb lets the pointer move back, so a class can see the effect within seconds.
Why is the case sealed and airtight?
The pressure from the bulb can only build up in a closed space. Because the case is airtight all round, the pressure you add stays around the capsule long enough for students to see the reading change.
What dial size and scale does it have?
The listing does not state them. Tell JLab the scale or unit you need, for example millibars or inches of mercury, and it will confirm what it can supply.
Is it different from the Barometer Demonstration Aneroid?
Both are teaching models in a clear case with a squeeze device to raise the pressure; that listing names a transparent acrylic case and a rubber bellow. Ask JLab to confirm the differences if they matter for your order.
Who manufactures this barometer?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of physics demonstration apparatus and school laboratory equipment, incorporated in 2017 with its works on Hargolal Road, Ambala, Haryana. This demonstration barometer is built in JLab’s own works and not bought from a trader, so schools, colleges, dealers and importers deal directly with the factory, each unit is inspected visually before dispatch, and repeat orders come from the same source. JLab exports worldwide and ships to buyers in every region — for example Estonia in Northern Europe, Laos in Southeast Asia, Yemen in the Middle East, Guyana in South America and Tajikistan in Central Asia.
