The Agr Polarimeter, used in accordance to ASTM C148-B, provides measurement of residual stress in annealed glass containers and glassware. This device offers a simple and reliable determination of residual stresses with measurable results that are objective and accurate, while eliminating material thickness limitations and strain disks.
- Glass bottle production – detect annealing and structural stresses
- Glass manufacturing – evaluate resultant temper stress
- Dual-mode operation permits use as a polarimeter or polariscope
- Measurement of retardation up to 565nm
- Compliant to ASTM C148-B
- Rotatable analyzer
- Retractable tint plate
