CanNeed-PLT-P200 Polarization Tester for Preform can detect the crystallinity and various defects of PET embryos, which is very suitable for preform manufacturers to analyze and improve the production process of PET preforms. 

1. It is easy to operate and measure accurately.

2. Crystallinity can be identified at any time.

3. Not only the colorful molecular birefringence deformation streamlines can be detected, but the black isodip line can be also seen when the pre-formed axis of the bottle embryo is parallel to the polarized optical axis of the tester.

4. The tester is equipped with a special removable angle panel that allows the sample to be placed quickly at 0 or 45 degrees, so that the corresponding test results can be obtained quickly and accurately.  

5. Configured LED light source, which is energy saving and low heat generation for long life using.
