Description

Hydrometer 20C – 700 – 800

This versatile hydrometer is designed for measuring the density of various liquids at a controlled temperature of 20°C (68°F). The 700-800 range on its scale caters to a broad spectrum of liquids, making it a valuable tool for various applications. Calibrated for accurate readings at 20°C, it offers a simple and effective solution for density measurement.

Function:

A hydrometer operates on the scientific principle of Archimedes’ Law. This law states that the buoyant force experienced by an object submerged in a fluid is equal to the weight of the fluid displaced by the object. In simpler terms, the hydrometer floats at a level dependent on the liquid’s density. Denser liquids cause the hydrometer to float higher on the scale, while less dense liquids allow it to sink deeper.

Key Features:

• Universal Application (within range): This hydrometer’s 700-800 scale allows it to measure the density of various liquids that fall within this density range. While some models may be designated for specific applications (e.g., petrol), this general-purpose hydrometer offers versatility for various needs.
• Temperature Calibration: The instrument is designed for optimal accuracy at 20°C (68°F). For accurate measurements at other temperatures, using temperature correction charts or specific gravity tables may be necessary (depending on the model).
• Weighted Bulb: The weighted bulb ensures the hydrometer floats upright in the liquid.
• Graduated Scale: The scale on the stem indicates the liquid’s density based on the floating depth of the hydrometer. Higher readings on the scale correspond to denser liquids.

Applications :

• Quality Control: Measuring the density of antifreeze, battery acid, or coolant solutions to ensure they meet the required specifications.
• Scientific Experiments: Determining the density of various liquids for scientific research or educational purposes.
• Food and Beverage Industry: Monitoring sugar content in syrups, brines, or other solutions (may require specific calibration).
• Alcohol Distilling (if scale allows): Measuring the alcohol content in spirits (requires specific calibration tables).
• General Liquid Density Measurement: Checking the density of unknown liquids within the 700-800 range for preliminary assessment (further testing might be required).

Benefits:

• Simple and Easy to Use: The hydrometer offers a quick and user-friendly method for on-site liquid density measurement.
• Precise Measurement (at 20°C): When used at the calibrated temperature, this instrument provides accurate density readings within its specified range.
• Portable and Versatile: The compact design makes it a practical tool for various applications.
• Cost-Effective: Hydrometers are a relatively inexpensive solution for density measurement compared to some electronic alternatives.

Using a Hydrometer:

1. Ensure the hydrometer and the liquid are at the calibration temperature (20°C).
2. Fill a clean container with enough liquid to allow the hydrometer to float freely without touching the sides or bottom.
3. Gently immerse the hydrometer into the liquid and allow it to settle.
4. Read the density value from the scale at the point where the liquid meets the hydrometer stem.
5. Consult the manufacturer’s instructions or a temperature correction chart if using a temperature different from 20°C.
6. For specific applications like alcohol content measurement, consult conversion tables or specific gravity information for the relevant liquid.
