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.

Penta Angle Prism are widely used in laser level, Image system, precision system, and optical area. For penta prism, the deviation angle of 90 is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled, we can produce high precision penta angle prism,and make coating according to customer's request.

Micro Pore Optic (MPO) is a kind of grazing incidence optical element, which can focus high-energy rays, such as X rays, ultraviolet light. MPO is a type of thin slice glass with porous structure. MPO is made up of millions of square shaped pores. The micro pore size is in micron scale and the surface of their inner wall has very low roughness. The shape of MPO can be divided into two classes: plane and sphere. The planar MPO can converge to the astigmatism, while the spherical MPO can converge to the parallel light. So far, in all known optical components of X ray, MPO not only guarantee the large field of view and high resolution, but also has the smallest volume and weight. In order to get the best focusing effect, we can coat surface of the micro pores inner wall with increasing reflective film, different application bands using the different film materials.
