I. Overview
The acid value, also known as the acid number, is a key indicator of the acidity level in oils and other substances. It represents the amount of potassium hydroxide (in milligrams) required to neutralize the free fatty acids present in one gram of oil or similar material. In fresh or refined oils, the acid value is typically low. However, improper storage, exposure to heat, or contamination can cause the acid value to rise over time. As a result, the acid value serves not only as a quality parameter but also as an important health indicator for oils.
The enhanced acid value rapid measuring instrument is specifically designed for the accurate determination of acid values in a wide range of oils, including rapeseed oil, peanut oil, soybean oil, corn oil, sesame oil, rice bran oil, tung oil, cottonseed oil, animal fat, petroleum, wax, and soap. This device eliminates the need for preparing standard alkali solutions or additional reagents, making it safer and more convenient to use. It is non-toxic, consumes minimal resources, and is user-friendly. The instrument allows for quick operation, with results displayed within just a few minutes. Its accuracy matches that of the current national standard method (GB5530-85), ensuring reliable and consistent measurements. Whether used in laboratories, production lines, or field settings, this tool offers a fast, efficient, and precise solution for acid value analysis.
