|---|---|---|---|
| This barometer (EL-SLE-4800) | Fortin’s (mercury column) | 675–820 mm Hg in 1 mm and 26.5–32.5 inch Hg in 0.05 inch; verniers read 0.05 mm and 0.002 inch | Brass (aluminium model available); 6 mm borosilicate tube; −10 to 50 °C thermometer; polished wooden board |
| Standard Fortin's Barometer | Fortin’s (mercury column) | 600–800 mm Hg and 0.05 mm Hg division (both listed as minimum) | Enamelled and lacquered brass case on a polished wooden board with wall-fixing plates; thermometer with Celsius and Fahrenheit scales, −16 to 46 °C (minimum) |
| Aneroid Barometer | Aneroid dial | 100 mm dial graduated 28–31 inch of mercury and 960–1060 millibars | Plated bezel, cover glass, plastic base |

Choose this model when students should read pressure directly from a mercury column, with vernier resolution on both a millimetre and an inch scale and a thermometer for the temperature correction. The Standard Fortin’s Barometer is listed with wall-fixing plates and a Celsius/Fahrenheit thermometer, while the aneroid models are dial instruments with no mercury column, which are simpler to hang and move for daily weather readings.
What Is a Fortin's Barometer Used For?
A Fortin’s barometer measures atmospheric pressure as the height of the mercury column that the air pressure supports in a closed glass tube. Before each reading, the mercury surface in the cistern is brought up to a fixed index point with the adjusting screw at the base, and the vernier is then set level with the top of the meniscus; the main scale plus the vernier gives the height in mm Hg or inch Hg. In schools it supports the topic of atmospheric pressure in class 8 science, the mercury barometer in class 11 physics (mechanical properties of fluids) and the weather-instruments practical in class 11 geography. College physics and geography labs use it as the room’s reference barometer, for example to record the pressure during gas-law and boiling-point experiments.
Hang the board vertically on an inside wall, away from direct sunlight, heaters and draughts, because the column must be plumb and at a steady temperature to read correctly. Note the attached thermometer each time you read the barometer: mercury and the scale both expand with temperature, so careful work corrects the reading to a standard temperature. Move the instrument as little as possible, and keep it out of reach of unsupervised students — mercury is toxic, and any spill should be cleaned up under the school’s chemical-safety procedure.
What to Specify When Ordering
- Model — the brass barometer on this page or the aluminium model.
- Scales — check that the dual mm Hg and inch Hg scales with verniers suit your syllabus or tender wording.
- Quantity — the minimum order is 10 units; add aneroid barometers or other weather instruments to the same enquiry if you are equipping a geography room.
- Filling and transport — ask how the barometer is filled and packed for shipment to your destination.
Frequently Asked Questions
What is a Fortin's barometer used for?
It measures atmospheric pressure in school and college laboratories. The pressure is read as the height of a mercury column on the scale, after the mercury level in the cistern has been set to the fixed index point.
What range and least count do the scales have?
The millimetre scale runs from 675 to 820 mm Hg in 1 mm divisions and the inch scale from 26.5 to 32.5 inch Hg in 0.05 inch divisions. With the verniers, readings can be taken to 0.05 mm and 0.002 inch.
Is a thermometer included?
Yes. The barometer comes with a −10 to 50 °C thermometer, which gives the temperature needed to correct a barometer reading for the expansion of the mercury and the scale.
Is it available in materials other than brass?
Yes. This listing is the brass model, and an aluminium model is also available. State which one you need in your enquiry.
How is it different from an aneroid barometer?
A Fortin’s barometer reads pressure from a mercury column with verniers, so it suits teaching the principle and taking reference readings. An aneroid barometer uses a sealed metal capsule and a dial, has no liquid, and is easier to move; JLab lists aneroid models separately, linked below.
Is the barometer supplied filled with mercury?
This listing does not state how the barometer is filled or packed for transport. Ask JLab when you enquire, because carriers and destination countries apply their own rules to shipments that contain mercury.
What information is needed for an export quotation?
Send the quantity, the model (brass or aluminium), 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 you are buying against 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 as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of physics and school laboratory instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Its Fortin’s barometers are built at JLab’s own works rather than bought in from a trader, so schools, colleges, dealers and importers order factory-direct, every barometer is visually inspected before dispatch, and repeat orders are handled by the manufacturer itself. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). JLab exports worldwide and ships to buyers in every region — for example DR Congo in Central Africa, South Africa in Southern Africa, Estonia in Northern Europe, Bahrain in the Middle East and Nigeria in West Africa. Buyers working to a school or college tender can find details on the JLab lab tenders page.
