Automatic polariscope YLY-H

digital

The YLY-H Intelligent Polarizing Stress Tester is suitable for polarized internal stress testing (ASTM C148 Polariscopic Examination) of glass containers. It is designed for testing glass infusion bottles, glass tube (molded) medicine bottles, injection bottles, ampoules, oral liquid bottles, and more. It can also be used for stress testing of glass containers such as beer bottles and liquor bottles.Product Features:Two test modes of Qualitative and Quantitative. The test space is adjustable and suitable for different kinds of bottles.The instrument can store 200 groups of data, each of which contains 50 measurements.Equipped with high precision core parts with test accuracy better than 2.0 nm.Touch screen display. The measurement angle and optical path difference can be displayed at the same time. Users can get the required data intuitively.Adopting absolute encoder, the dark field of polarization field is always at zero angle, so there is no need for users to zero calibration, which avoids the error caused by human operation.The energy-saving and environmental protection LED light source is adopted, which saves more than 80% energy compared with the traditional light source.Equipped with micro printer to print out test data conveniently.It is equipped with USB interface and can connect PC software.Automatically save historical test records, local query, and export to EXCEL format on the computer.Three-level authority management, fully meet the GMP authority authentication.Testing Record Auditing and Tracking Functions.Test results are uploaded synchronously to cloud servers for storage, and can be browsed on the Internet around the world.Dual backup of local data and cloud data to ensure that data will not be lost.Test 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.Test Standards:This test instrument conforms to many national and international standards: GB/T 4545, GB/T 12415, JJG196-2006, YBB00032005-2005, YBB00332002-2015, YBB00162003-2015.Technical Specifications:Indicative Value of Instrument: 0.1 nmMeasurement Accuracy: 2nmDiameter of Polarizing Field: 150mmRotation Angle of Analyser Plate: -180 ~ +180°Edge Brightness of Light Field: ＞120cd/mBrightness of Light Field: ≥800luxNumbers of Data: 200 group, 50 measurements / groupInstrument Dimension: 220mm(W) x 350mm(D) x 580mm(H)Power Supply: AC 100-240V 50/60Hz (can be changed to local requirement)Net Weight: 9 kgConfigurations:Instrument, Micro Printer, Professional Software, USB Communication Cable
