Principle and characteristic of automatic acid value tester

Automatic acid value tester is a special equipment used to determine the acidity of liquid samples, its principle and characteristics are as follows:

How it Works:

The automatic acid value tester is based on the principle of acid-base neutralization reaction. In general, acidity can be determined by determining the amount of acidic substances present in a liquid sample. The device uses acid-base indicators (such as phenolphthalein indicators) as indicators, and its color changes in acidic and alkaline environments. At the same time, the acid value tester is equipped with an automatic titration device and potentiometer, which can accurately determine the size of the acid value. By means of automatic titration, a liquid sample containing an acidic substance is titrated with a alkali solution. When the acidic substance in the solution is completely neutralized, the potentiometer can detect the change and thus determine the acid value.

Features:

1, full automation: automatic acid value tester can achieve automatic titration process, greatly improve the test efficiency and accuracy, reduce manual error.

2, high precision: the equipment is equipped with high-precision potentiometer and automatic titration device, can real-time monitoring of the acid-base titration process changes, provide accurate and reliable test results.

3, multi-functional: automatic acid value tester can be used for acidity test of various liquid samples, including food, beverage, cosmetics, pharmaceuticals and other fields, with a wide range of applications.

4, flexibility: the equipment can flexibly adjust the titration speed and titration quantity to adapt to the test needs of different samples.

5, data processing: Acid value tester is usually equipped with data processing software, can automatically record and analyze the test results, generate reports, convenient for users to conduct data management and analysis.

In short, the automatic acid value tester realizes the accurate determination of acidity in liquid samples by means of automatic titration and potentiometer measurement. It has the characteristics of high efficiency, accuracy and flexibility, and is widely used in the quality control and detection field of various industries.
