Glass Bottle Polarizing Stress Test Machine is suitable for testing polarized internal stress of glass infusion bottle, glass tube medicine bottle (moulded), tube (moulded), injection bottle, ampoule bottle, oral liquid bottle, etc. It can also be used for stress testing of glass containers such as beer bottle and liquor bottle.
Features
Adopts two test modes: qualitative and quantitative. Testing area can be changed.
Preserve 200 groups of data with 50 measured values in each group.
Accuracy of high-precise absolute angle encoder is more than 2.0nm.Â
Touch interface can display the measurement angle and the difference of optical path.
Automatic calibration of dark-filed avoids the errors caused by manual operation.
Application of Energy Saving Green Design in LED light is advanced.
It is equipped with micro-printer to output test data conveniently.
PC software connected with USB interface controls the operation of the instrument.
Save the test records automatically, query locally and export them to the computer in excel format.
GMP management of users?? three-level authority is settable.
Functions of auditing and tracking test records audit are available.
The data is synchronously uploaded to the cloud server for storage and can be browsed on the Internet.
The dual backup of local and cloud data is optimal.
Principle
The tester uses the principle of polarized light interference to check the internal stress of the glass or the birefringence effect of the crystal. As the polarizing stress meter has sensitive color plates and uses 1/4 wave plate compensation method, the instrument can not only measure the difference of the optical path of glass qualitatively or semi-quantitatively according to the interference colour sequence in the polarizing field but also gauge the internal stress accurately with wall thickness.
