The surface stress meter ( Ref. ASM-200-FAP measures surface stress of tempered glass and the depth of the stress layer according to photoelastic technology by letting light spread along the glass surface. This machine is equipped with a PC, which can reduce measurement errors caused by the operators . Moreover, it is more convenient for the management of testing data. Thickness Gauge is optional to improve the measurement efficiency.

Features
Advanced non-destructive testing method : Photoelastic analysis Refractormeter
determination of qualified or unqualified (OK/NG ) according to operators setting( in continuous testing mode )
quantity accumulation of OK and NG samples automatically
offer master piece to achieve self-calibration at any time
Automated testing to ensure detecting accuracy and stability
Data saved by PC to facilitate data analysis, providing guide for quality control
Optional single testing mode to save testing time
Recommended manual testing mode when samples are not in good tempered condition
Led Lamp with 10,000 hours serving time
automatic dripping device and automatic suction device controlled by specific software has been integrated into the body to save installation space
