Product Description: Specific Gravity Glass Hydrometer 1.300–1.400
The Specific Gravity Glass Hydrometer 1.300–1.400 is a precision measuring instrument designed to measure the specific gravity or relative density of liquids. Made from glass, this hydrometer is suitable for laboratory testing, industrial applications, quality control, and educational purposes. Its measurement range of 1.300 to 1.400 makes it useful for analyzing liquids whose specific gravity falls within this range.
A hydrometer works on the principle of buoyancy. When placed in a liquid, it floats at a level determined by the liquid’s density. The specific gravity can then be read from the graduated scale at the liquid surface, following the manufacturer’s instructions. This provides a convenient method for determining the relative density of liquid samples without requiring complex measuring equipment.

How to Use a Specific Gravity Glass Hydrometer
- Select a clean measuring cylinder tall enough for the hydrometer to float freely.
- Pour the liquid sample into the cylinder without creating excessive bubbles.
- Gently lower the hydrometer into the liquid.
- Allow it to float freely without touching the sides or bottom.
- Read the scale at the correct liquid level according to the manufacturer’s instructions.
- Record the result and clean the instrument appropriately after use.
Always check the specified calibration temperature because temperature differences can affect liquid density and the reading.

Frequently Asked Questions (FAQ)
Q1: What is a Specific Gravity Glass Hydrometer 1.300–1.400 used for?
It is used to measure the specific gravity of liquids that fall within its measurement range.
Q2: What does the range 1.300–1.400 mean?
It indicates the range of specific gravity values the hydrometer is designed to measure, from 1.300 to 1.400.
Q3: What material is this hydrometer made from?
It is made from glass, so it should be handled carefully to prevent damage or breakage.
Q4: Does this hydrometer require electricity?
No. It operates using the principle of buoyancy and does not require batteries or an electrical power supply.
Q5: How do I obtain an accurate reading?
Allow the hydrometer to float freely in the sample, avoid contact with the cylinder walls, read the scale according to the manufacturer’s instructions, and observe the specified calibration temperature.
Q6: Can it measure every type of liquid?
No. The liquid’s specific gravity must fall within the 1.300–1.400 range, and the instrument must be suitable for that particular liquid and testing method.
Q7: Where can this hydrometer be used?
It is suitable for laboratories, industrial facilities, educational institutions, and quality-control environments requiring specific gravity measurements.
