The significance of the existence of acid value testers

Thread Content

The acid value tester is a fully automatic measuring instrument that accurately determines the acid value of insulating oil using the extraction method. While improving work efficiency and testing accuracy, this instrument minimizes operators’ exposure to samples and reagents, thereby greatly ensuring their personal safety. During measurement, simply pour the sample into the sample cup and place the cup into the sample cup hole. The instrument will then automatically perform operations such as searching for the sample, injecting the extractive solution and performing blank titration, measurement, automatic cleaning and shutdown, and displaying and printing the results. One startup allows for the determination of 1 to 3 samples; it is easy to use and highly efficient. The acid value tester comes with standard acids and calibration procedures for calibrating the instrument. Users can calibrate both the instrument and the neutralizing solution at any time, thereby overcoming the drawback of concentration changes in the neutralizing solution during use ； During measurement, the instrument automatically subtracts the background value of the extract, thereby overcoming the effect of changes in the background value during the use of the extract on the results. This makes the test results more accurate and reliable.
