Aneroid Barometer Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4820
Jlab Export is a leading Aneroid Barometer Manufacturer,and suppliers in India
Aneroid Barometer (code EL-SLE-4820) is a dial barometer used for measuring atmospheric pressure in school physics and geography labs. Its 100 mm dial carries two scales, 28 to 31 inches of mercury and 960 to 1060 millibars, so students can read the same pressure in either unit and compare them. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Barometers?
| Model | Type | Dial or scale | Other listed details |
|---|---|---|---|
| This barometer (EL-SLE-4820) | Aneroid, dial | 100 mm dial; 28–31 inHg and 960–1060 mbar | Bezel, cover glass and index; plastic base |
| Barometer Aneroid Wall Mounting | Aneroid, wall mounting | 100 mm dial graduated in inches and millibars | Mounted in a plastic case 150 mm in diameter |
| Aneroid Barometer (physics lab listing) | Aneroid | Measuring range 760–1050 hPa | No other details listed |
| Barometer Demonstration Aneroid | Aneroid, demonstration | Not stated | Transparent acrylic case shows the movement; supplied with a rubber bellow that raises the pressure when squeezed |

Choose this model when you want a compact dial barometer with both inch-of-mercury and millibar scales for a bench or weather table. The wall-mounting model hangs in its own case, the demonstration model lets a class watch the mechanism move, and the Fortin’s barometer is the mercury-column instrument for labs that teach reading a mercury column with a vernier.
What Is the Aneroid Barometer Used For?
“Aneroid” means without liquid: inside the case a sealed, partly evacuated metal capsule flexes slightly as the air pressure rises or falls, and a lever system turns the pointer across the dial. In school science it shows that air exerts pressure and that this pressure changes from day to day, and it is one of the weather instruments in class 11 geography practical work alongside the thermometer, hygrometer and rain gauge. Physics teachers use it with the topic of pressure in fluids, and students keeping a weather log record the reading each morning to see how falling pressure tends to come before unsettled weather and rising pressure before settled conditions. Because air pressure also falls with height, a class can compare readings taken on the ground floor and the top floor of a tall building.
Keep the barometer on a level surface or at eye level, away from heaters, direct sun and draughts. Tap the cover glass lightly before reading so the pointer settles, then set the index over the pointer to mark the reading; the next day the gap between index and pointer shows how far, and in which direction, the pressure has moved. Weather reports normally quote pressure corrected to sea level, so at higher altitudes this barometer will read lower than the published figure.
What to Specify When Ordering
- Model — this dial barometer, the wall-mounting version, or a demonstration barometer with a transparent case.
- Scales — this listing reads 28–31 inHg and 960–1060 mbar; if a tender names a different range or unit, include it so JLab can confirm which model matches.
- Quantity — the minimum order is 10 barometers; plan one per lab or school weather station.
- Other weather instruments — add a hygrometer, rain gauge or thermometer to the same enquiry if you are equipping a school weather station.
Frequently Asked Questions
What does an aneroid barometer measure?
It measures atmospheric pressure without any liquid. A sealed metal capsule inside the case expands or contracts as the air pressure changes, and the movement is shown by the pointer on the dial.
What range does the dial of this barometer cover?
The 100 mm dial is graduated from 28 to 31 inches of mercury on one scale and from 960 to 1060 millibars on the other, which spans normal weather changes at low-lying sites. Air pressure falls with altitude, so a school at high altitude should state its elevation in the enquiry so JLab can confirm whether this dial suits it.
Is a millibar the same as a hectopascal?
Yes. One millibar equals one hectopascal, so the millibar scale can be read directly in hPa, the unit used in many weather reports and textbooks.
How is it different from a Fortin’s barometer?
A Fortin’s barometer measures pressure by the height of a mercury column read with a vernier, while this aneroid barometer uses a metal capsule and a dial. The aneroid type contains no mercury and is lighter and easier to move between rooms, which suits school use; the mercury barometer is used where students learn to read and correct a mercury column.
Why does my reading differ from the weather forecast?
Forecasts usually give pressure corrected to sea level. A barometer at a higher altitude reads the actual local pressure, which is lower, so compare changes over time rather than the exact figure.
Can this barometer be hung on a wall?
The listing describes a dial barometer with a plastic base and does not state a wall fitting. JLab lists a separate wall-mounting aneroid barometer in a 150 mm plastic case, linked below.
What should an export enquiry include?
Give the quantity, the destination country and port or city, your preferred delivery terms such as FOB or CIF, any packing or labelling needs, and the tender reference if the order is for a tender.
Who manufactures this barometer?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of school physics instruments and laboratory equipment in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The aneroid barometer is produced in JLab’s own works rather than sourced from a trader, so schools, colleges, dealers and importers buy direct from the maker, every barometer is checked visually before packing, and repeat orders are handled by the same factory. The company holds GSTIN 06AADCJ9848D1ZE and Legal Entity Identifier 549300DTGS77DGYD6N03. JLab exports worldwide and ships to buyers in every region — Latvia in Northern Europe, Botswana in Southern Africa, Liberia in West Africa, Slovenia in Southern Europe and Luxembourg in Western Europe are a few examples. Schools buying through tenders can find details on the JLab lab tenders page.
