The KDSZ-803G fully automatic acid value analyzer is a high-precision and digital industrial instrument developed by our company's scientific research and technical personnel, leveraging their own advantages and through long-term unremitting efforts. The machine is easy to operate and has a beautiful and elegant appearance. The instrument adopts automatic digital microcomputer control, based on the basic framework of acid-base neutralization reaction in chemical analysis, and is equipped with a self-developed background blank deduction and titration endpoint logic judgment program, so the precision and accuracy of the measurement are good.

The detection of oleic acid value in transformers and steam turbines is a routine inspection item for oil filled electrical equipment in power systems and industrial and mining enterprises. The KDSZ-803G fully automatic acid value tester is a specialized equipment developed by our company for the determination of acid value in the above-mentioned oil products. This instrument is based on a single-chip microcomputer and integrates multidisciplinary technologies such as optics, mechanics, electronics, and chemistry. Replacing manual operation not only improves work efficiency, but also reduces the labor intensity of operators and minimizes the harm of organic solvents and other chemicals to human health.
 
The KDSZ-803 fully automatic acid value analyzer adopts the principle of neutralization method. At room temperature, the microcomputer controls the automatic completion of liquid addition, stirring, titration, and endpoint determination. Adopting a touch sensitive LCD screen to select all working parameters, the human-machine dialogue interface is simple and friendly, easy to operate, and the average oil sample analysis cycle is about 2 minutes. It can display 100 sets of measurement results separately and print out multiple parameters related to the measurement.

Use good reagent bottles to contain extraction and neutralization solutions. The extraction solution is stored in a hard plastic container. The neutralization solution is stored in polyethylene plastic bottles to avoid the possibility of reaction between caustic potassium and glass. In addition, we have independently developed a neutralization liquid balance gas purification device, which avoids the influence of carbon dioxide and water vapor on the concentration of the neutralization liquid. During the operation, users do not need to touch organic solvents with their hands, reducing the harm of chemicals to the human body.

 

1. Color touch screen, with simpler and more user-friendly operation.
2. The instrument is controlled by a large capacity microcontroller, which ensures stable and reliable operation.
3. The instrument is equipped with a wide range watchdog circuit to prevent system crashes.
4. The instrument is divided into three cups and six cups. During testing, simply place the oil sample in the designated position, and the instrument will automatically add liquid for extraction, titration and stirring, endpoint detection, and result printing. It not only reduces the contact between the human body and the medication, but also improves work efficiency.
5. The instrument adopts photoelectric detection and automatically deducts the background to make the detection results closer to the true value.
6. Portable structure, easy to move, convenient for both indoor and outdoor use.
