Strainoptics GASP-LWC-HS Grazing Angle Surface Polarimeter—Glass Surface Stress Strainoptics GASP-LWC-HS Grazing Angle Surface Polarimeter—Surface Stress in Glass This is an impressive-looking instrument, like a throwback to the days of sextants and phrenology. The laser works, and the battery takes and holds a charge. The prism on the bottom has some scuffing on it. The mirror is unscratched. Picture 5 shows the laser (thin red line). The instrument was last calibrated in May of 2013. The set comes with the following: Laser GASP Surface stress CAL-plate Standard compensator AC charger 40% full bottle of index matching fluid Practice sample glass plate User's manual Padded carrying case Strainoptics' GASP® Polarimeter is a portable instrument for measuring surface stress in heat-strengthened and tempered glass. It can also be used to confirm stress-relief in annealed glass and to validate furnace settings for manufacturers of safety glass. The standard GASP model is for flat or slightly curved surfaces, while the GASP-CS version is designed to accommodate a curvature greater than 8 inches (200 mm). Both models may be ordered with either a laser or fiberoptic light source. The laser model features a rechargeable battery pack and offers the broadest range of measurement, up to 25,000 psi (180 MPa). Strainoptics’ GASP® polarimeters are: Non-destructive Easy to operate Compliant with all industry specifications, including ASTM C1048, C1279 and the new compulsory EN-12150 and EN-1863 standards and CE marking requirements for testing mechanical strength in architectural glass For in-plant or field use Available for flat or curved surfaces Ideal for solar glass applicationsRemember: I'm not an expert on any subject. With regard to the equipment I sell, I am a full-time amateur and part-time idiot. My descriptions are simply accounts of my findings and observations while fumbling around with whatever contraption happens to come my way. They are not guarantees, warranties, endorsements, or Good Housekeeping Seals of Approval. Buy it or don't. Leave me out of the decision making process. A simple rule to follow on these auctions: Imagine that you're buying from an untrained monkey. With maybe better hygiene. Please email any questions. All equipment is entrusted to the smartest, most capable employee for testing. (OK, I work alone. Sue me.) In most cases, I can ship as soon as payment is received. As always, local pickups are welcome, at no charge! Thanks for looking!
