Hydrometer

A hydrometer is a floating instrument used to assess liquid density or specific gravity using its calibrated scale. This listing offers three range labels; confirm their units and intended liquid application before selecting an option.

For laboratory demonstrations or compatible liquid measurements, a suitable hydrometer lets you observe a scale reading while it floats freely in a sample container.

Listed product details

• Product: hydrometer.
• Construction: weighted glass bulb and graduated stem, as described in the existing listing.
• Range option labels: 01-10, 10-20 and 40-50.

Selecting the correct range

The option labels do not identify the scale system, units, decimal placement or calibration temperature. Do not assume they represent specific gravity, density, alcohol percentage or another scale. Confirm the exact markings and intended application with the supplier before ordering.

A general hydrometer listing does not establish suitability for battery electrolyte, alcohol solutions or milk testing. These applications require an appropriate scale and compatible instrument.

Measurement notes

Use a compatible container deep and wide enough for the instrument to float without touching its base or sides. Follow the manufacturer's instructions for sample temperature, meniscus reading and any correction requirements. A measuring cylinder is not documented as included.

Specifications and care

Manufacturer, dimensions, scale resolution, accuracy tolerance and calibration certificate are not specified. The earlier 0.3 kg figure is not identified as instrument or packed weight. Handle the glass carefully, inspect for damage and follow suitable laboratory handling and cleaning procedures for the liquid being measured.
