Overview

　　HK-258A automatic diesel acidity tester, in line with the requirements of GB/T 258 test method, is suitable for the determination of diesel acidity using color indicator

titration.

Functional features

1. Detection mode: using industrial digital camera - machine vision technology and automatic control technology, one key to start the completion of automatic cleaning,

automatic heating, boiling condensation reflux, automatic filling indicator, automatic stirring, automatic completion of the titration of two samples, automatic judgment

of the end point, the completion of the determination of the average acidity value of the two specimens is automatically generated

2. Digital camera: ≥ 200,000 pixels, color imaging, real-time access to the color of the sample being measured, connected to the image processing system and automatic

control system to achieve real-time transmission of images, rapid response to avoid time delays caused by experimental errors

3. Image processing system: real-time image color identification and processing, according to the pixel distribution, brightness and other information, including RGB, HSV

two different color space model to describe the color channel, the extracted color information for separation, linear, fuzzy, color fitting and other related operations, to get

the end point to keep the color difference (Color Difference of the Reserved End Point Color). Reserved End Point Color), and the end point color comparison in the

background database to complete the end point determination and feedback.

4. Automatic control system: through the electronic master controller, control image acquisition, titration and titration rate, stirring, heating, boiling condensation reflux

and other units

5. Light source: instrument titration chamber built-in light source, to ensure the color reproduction, color temperature 6500K ± 100K

6. Screen display: 10-inch high-definition color touch LCD screen, real-time display of the titration status
