Product Description

PST-02 ASTM C148 Glass container optical retardation polariscope strain viewer 

PST-02 ASTM C148 Glass container optical retardation polariscope strain viewer  is suitable for measuring the internal stress value of glass products such as various glassware, glass measuring tools, glass containers, glass bottles for medicine and food packaging, etc.



Technical Features

• 5-inch colorful LCD display
• Double test modes: qualitative and quantitative.
• Uses an angle encoder for measurement, and the measurement result is better than 2nm, no calibration required for dark field
• Display polarizing stress date automatically: Enter the thickness value, calculate the stress value and temper number directly
• Five groups of data are displayed: analyzer rotation, optical retardation, stress value (retardation unit thickness), apparent temper number and real temper number
• Equipped with micro-printer to print test result fast
• Standard RS232 data communication interface, which is convenient to PC connection and data transmission (optional)

Test Principle
Polarizing Stress Tester is an instrument for examining the effect of internal stress or crystal birefringence of glass by using polarized light interference principle. Due to the polarizing stress analyzer equipped with sensitive customers. And the application of 1 / 4 wave plate compensation method, so the instrument can not only according to the polarization field in the order of interference color, internal stress of qualitative or semi quantitative measurement of the glass, you can also accurate quantitative measurements of glass stress value.
