Nicholson Hydrometer
Product Code : LSK-POM-11183
Nicholson Hydrometer (SKU LSK-POM-11183) is a constant-immersion hydrometer made from brass sheet: a hollow metal cylinder floats upright, with a loading pan on top and a bucket hanging below that keeps it stable and holds the specimen. It is used for density and relative density of both solids and liquids in Class 11 physics and college labs. Science Lab Supplies builds it in two sizes at its Saha, Ambala factory (Plot 448, HSIIDC Industrial Area, India) and supplies schools, colleges, tender contractors and distributors directly.
Specifications
Shown below is the complete specification of the Nicholson hydrometer. In short, it is a hollow brass-sheet cylinder with an upper loading pan and a lower bucket that adds stability and carries the specimen under the liquid, and it is offered in medium and large sizes for solid and liquid density work.

Applications and Experiments for the Nicholson Hydrometer
The Nicholson hydrometer is always sunk to the same mark, so the masses needed on its pan reveal the weight of a small solid and its loss of weight in water, or the density of a liquid. It supports Class 11 physics and B.Sc. hydrostatics practicals on relative density.
- Class 11 physics: relative density of a small solid, adding masses from a Physical Weight Box Of 100gm Iron Chrome Plate to the upper pan.
- Testing specimens such as the Metal Cubes first on the pan and then in the bucket.
- Density of a liquid by floating the hydrometer in water and then in the liquid, and checking the result with a Specific Gravity Bottle.
- B.Sc. hydrostatics: the principle of flotation in a constant-immersion instrument.
Standard Scope of Supply
The Nicholson Hydrometer is supplied as a single instrument, the brass-sheet cylinder with its upper loading pan and lower bucket, in the medium or large size you choose. Masses, a tall liquid jar and test specimens are not part of the item and can be listed as optional lines on the quotation.
Packing, MOQ and Lead Time
Tell Science Lab Supplies which size you need, medium or large, and how many, and it will send a quotation stating packing, delivery time and price for that order. Weight boxes or density specimens for the practical can be added to the same quotation.
Because it holds an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. Name the size and quantity on the contact page, collect related apparatus in the enquiry cart, or follow the lab tender page for institutional bids.
Frequently Asked Questions
What sizes are available?
The Nicholson hydrometer is available in two sizes, medium and large. State the size on your enquiry and the quotation will be prepared for that model and quantity.
Can it measure both solids and liquids?
Yes. It is intended for solid and liquid density experiments: a solid is weighed on the pan and then in the immersed bucket, while a liquid is compared with water using the same fixed immersion mark.
What is the bucket at the bottom for?
The suspended bucket lowers the centre of gravity so the hydrometer floats upright and stable, and it holds the specimen under the liquid when its loss of weight is being measured.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures both sizes from brass sheet at its factory in Saha, Ambala, India. Buyers therefore obtain prices and delivery terms from the original maker, not from a trader.
