The polarizing stress tester for seasoning glass bottles can be widely used for internal stress measurement of glass products such as ampoules, oral liquid bottles, penicillin bottles, infusion bottles, wine bottles, seasoning glass bottles, canning bottles, etc.
Condiment glass bottle polarizing stress tester and internal stress detector
Scope of application:
Normally, glass is an isotropic homogeneous material that exhibits anisotropy when subjected to stress, resulting in birefringence of light.polarizing stress meterAccording to national standards, it can be widely used for internal stress measurement of glass products such as ampoules, oral liquid bottles, penicillin bottles, infusion bottles, wine bottles, seasoning glass bottles, canning bottles, etc.
Testing principle:
An instrument that uses the principle of polarized light interference to check the internal stress of glass or the birefringence effect of crystals. Due to the presence of sensitive color plates and the use of a 1/4 waveplate compensation method in the polarization stress meter, this instrument can not only qualitatively or semi quantitatively measure the optical path difference of glass based on the interference color sequence in the polarization field, but also accurately measure the internal stress value of glass when combined with a wall thickness gauge.

Technical Indicators:
The device adopts a 4.3-inch color LCD display screen for operation.
Qualitative testing mode, quickly determine the presence or absence of stress. Quantitative testing mode, digital display of optical path difference, quantitative evaluation of stress.
The brightness of the light field can be adjusted according to the laboratory environment.
Intelligent operation, no need to manually convert the optical path difference through the angle of the polarizer.
Input the thickness value of the specimen, and the average thickness optical path difference can be automatically calculated.
The LCD display screen has permission management function.
Technical parameters:
