The AEM-01 Automatic Edge Stress Meter adopts the photoelastic principle to measure the edge stress of glass according to ASTM C 1279-13. The meter can be applied to laminated glass, annealed glass, heat-strengthened glass, and tempered glass.
The glass that can be measured is from clear glass to tint glass (vg10, pg10). Painted glass after being polished with sandpaper can also be measured. The meter can measure Architectural glass, Automotive glass(windshield glass, sidelites, backlites and sunroof glass ), and solar patterned glass.
The edge stress meter can measure the stress distribution (from compression to tension) at one time with a speed of about 12Hz and the results are accurate and stable. It can meet the requirements of rapid and comprehensive measurement and testing in factory production. With the features of small size, compact structure and easy to use, the meter is also suitable for quality control, spot check and other requirements.
For the hardware, there are a sample measurement port, a positioning block and three positioning points. The probe head is directly connected to the computer through USB2.0 interface.
For the software, AEM-01 Automatic Edge Stress Meter (short for AEM), providing all the operation functions such as setting, measurement, alarm, record, report and so on.
