I. Overview and Technical Index

1. Overview

HZCS-N3 transformer oil acid tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value. This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents.

The instrument will automatically search the samples, inject the extraction, make a blank titration, do an experiment, clean off, display printing results and other operations as long as the operator put the sample cups in the sample cup holes and inject the extraction in the cup. Once started, 1 to 3 samples can be measured, which is convenient and high efficiency.

Because of the preparation of the standard acid for instrument calibration and calibration procedure, the clients can calibrate the instrument and the neutralizing liquid at any time so that the instrument can overcome the defect of changes in concentration of neutralizing liquid during use. At the same time, during the test the instrument will automatically deduct the background value of the extract so that the instrument can ignore the influence from the change of background value on the extraction. All these design make the result more accurate and reliable.
