Beck hydrometer is a specific type of hydrometer used to measure the relative density of liquids that are less dense than water. Here are the key points about a Beck hydrometer:
- Purpose: Measures the relative density (specific gravity) of liquids less dense than water.
- Graduation: It is graduated in degrees Beck (°Beck).
- Formula: The relationship is defined as
\( \text{°Beck} = 200 \times (1 – \text{relative density}) \) .
Characteristics:
- Scale: The Beck hydrometer has a scale specifically calibrated to measure degrees Beck.
- Application: It is commonly used in various industries where precise measurement of the density of lighter-than-water liquids is required.
Usage:
- Preparation: Ensure the liquid to be measured is at the standard temperature, usually 20°C, as density measurements can vary with temperature.
- Immersion: Carefully immerse the hydrometer in the liquid without it touching the sides of the container.
- Reading: Read the degree Beck value at the point where the liquid surface touches the hydrometer scale.
In summary, a Beck hydrometer is a specialized instrument for determining the relative density of less dense liquids, providing readings in degrees Beck.
