Tube opacity tester

Tube opacity testerCan be used to determine the opacity of plastic pipes and fittings (displayed as a percentage). This instrument adopts industrial touch screen control and touch screen operation. It has the functions of automatic analysis, recording, storage, and display.

Tube opacity testerWidely used in scientific research institutions, colleges and universities, quality inspection departments, and production enterprises.It is a device used to measure the transmittance of pipes, mainly applied in the production and quality inspection of pipes made of materials such as plastic, rubber, glass, etc. Specifically, it can be used in the following areas:

(1) Pipe manufacturing: The light transmittance of pipes is an important indicator for measuring the quality of pipes, as it directly affects the scope of application of pipes. The tube transmittance tester can help manufacturers determine whether the transmittance performance of the tube meets the requirements, thereby ensuring the quality of the tube.

(2) Quality inspection: The light transmittance of pipes is also an important indicator for pipe quality inspection, as it can reflect the material composition and processing technology of pipes. The tube transmittance tester can help quality inspectors determine whether the tube meets national or industry standards, thereby ensuring the quality of the product.

(3) Research and development: In the development of new materials and pipe design, pipe transparency is also an important reference indicator. This instrument can help R&D personnel understand the transparency performance of new materials, thereby providing a basis for the design of pipes.
