Microcomputer automatic acid value tester

summary:

The microcomputer acid value tester is designed according to the standards of GB / t7304 petroleum products and lubricants acid value determination (potentiometric titration) and GB / t18609 determination of original oleic acid value (potentiometric titration).
The microcomputer acid value measuring instrument is composed of three parts: host (hardware circuit and transmission machinery), imported titration device and computer. With the support of application software, the host can realize automatic titration, automatic replenishment and automatic determination of acid value in petroleum products. The key components of the instrument are imported devices. The whole machine has the characteristics of simple structure, beautiful appearance, high degree of automation and accurate analysis results. It is an ideal intelligent instrument necessary for petrochemical laboratories, oil analysis rooms and scientific research departments in Colleges and universities.

Technical parameters:

L windows operating system, the operation adopts man-machine dialogue mode, the steps are clear, simple and easy to operate.
The titration device is an original imported exchange unit (Swiss Wantong), with stable and reliable performance and extremely low transmission noise.
L automatic cleaning, automatic fluid replenishment, constant value fluid addition, mechanical and electrical organic combination.
Multi parameter setting and correction make the analysis of different kinds of samples easier, faster, shorter analysis time and more accurate.
The titration results and data can be stored and printed automatically, and complete titration data can be provided for analysis and research.
With double high resistance input, the electrode potential is more stable and reliable.
