What formula is used with the second type of lactometer graduated from 0 to 100 degrees for specific gravity determination?

The formula used with the second type of lactometer, which is graduated from 0 to 100 degrees for specific gravity determination, is based on the relationship between the lactometer reading and the specific gravity of the liquid being measured. In this case, the appropriate formula is designed to adjust the reading so it accurately reflects the specific gravity of the milk or milk product.

The correct formula, which incorporates a multiplication factor, takes into account that the lactometer reading needs to be adjusted based on a specific constant to ensure accuracy. When the milk’s density is being measured, this particular adjustment (0.29) is used to derive the specific gravity in a more precise way given the characteristics of milk.

By applying the formula, the lactometer reading is translated into a specific gravity value that accurately reflects the actual density of the milk, which is crucial for quality control and ensuring product safety in the dairy industry.

Contextually, other formulas may not provide the necessary adjustments specific to this type of lactometer reading. For instance, those that simply add or subtract without the appropriate constant may yield inaccurate specific gravity values. The correct approach ensures compliance with standard practices in public health sanitation concerning dairy products.
