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 acid value is the trace value of potassium sulfate that neutralizes the petroleum acid in 1g of oil, which contains a certain amount of inorganic acid and inorganic acid. The acid value includes organic and inorganic acids contained in the oil. In most cases, oil does not contain mineral acids. Therefore, the oleic acid value actually represents the content of organic acids in the oil. The organic acid contained in the new oil is mainly cyclonic acid. In the oil and in the process of use, the acid value of the oil produced by oxidation is an indicator to measure the degree of refining of the new oil. Whether the oil is running is an important indicator of the continued use of oil quality equipment.

ZXE-E Type Automatic Cardiovascular Function Diagnostic Meter
(1) Integrated Design
Automatic Cardiovascular Function Diagnostic Meter is based on the principle of pulse pressure according to the theory of the model sub-room network analysis about elastic chamber model of human circulatory system and the formula derived by a linear correlation algorithm. These formulas will be able to reflect cardiac function, vascular status, blood status and microcirculation function in 35 cardiovascular function parameters and the 64 pieces of professional aided diagnostic information through the non-linear compensation and parameter modification from clinical experience.

Automatic Cardiovascular Function Diagnostic Meter is a latest diagnostic equipment in the market with its feature "portable integration" model, and a total weight 3Kg, size 420 í- 260 í- 130 (slant) mm. The panel of the Analyzer is embedded 7 "blue backlit LCD screen and touch buttons; the front of the ramp is embedded high-speed thermal printer to provide menu and print the report in Chinese. If the products is for export, we can change the menu in other languages.

Automatic Cardiovascular Function Diagnostic Meter (integrated design) is light and portable, simple to operate, with reliable quality, elegant style, and low prices, which is very popular with customers. It is especially suitable for volunteer team activities to promote medicine and health products. The integrated design is one of the best-selling model at present.

It has truly professional and portable integrated design.

The system consists of dedicated computer, bright liquid crystal display modules, special micro-thermal, printers, and pulse sensors .

With auto-detection of 35 cardiovascular function parameters, and 64 pieces of exported diagnostic information, the Automatic Cardiovascular Function Diagnostic Meter can automatically print diagnostic report.
