Hydrometer 20C – 750 – 800

The Hydrometer 20C – 750 – 800 is a specialized tool designed to measure the density of liquids. Understanding its components and functionalities will equip you to utilize it effectively in various applications.

Components:

• Glass Body: The primary structure is typically made of borosilicate glass, known for its durability, resistance to chemicals, and clarity for easy reading.
• Weighted Bulb: The bottom part contains ballast, ensuring the hydrometer floats upright in the liquid.
• Scale: Etched along the stem is a scale marked with graduations (750 to 800 in this case). The specific scale type (e.g., specific gravity, Brix, Baume) will vary depending on the manufacturer and intended use.
• Meniscus: This is the curved line at the top of the liquid where it meets the hydrometer stem. The reading is taken at the lowest point of the meniscus for accurate measurement.

Functionality:

1. Temperature Calibration: The “20C” designation indicates the instrument’s calibration temperature. For optimal accuracy, the liquid being measured should ideally be at 20 degrees Celsius. Deviations from this temperature might require temperature correction factors provided by the manufacturer.
2. Range and Scale: The 750-800 marking specifies the working range of the hydrometer on the chosen scale. Readings within this range will provide the most accurate density values.
3. Reading the Measurement: Fill a tall, narrow cylinder with the liquid of interest. Gently immerse the hydrometer, ensuring it floats freely without touching the sides. Once settled, observe the position of the meniscus on the scale. This value corresponds to the liquid’s density based on the specific scale used.
