This type is adapted to measure stress onto a glass surface ranging from 0 to 150 MPa (MN/m2). With this Babinet-type, uniform measurements can be achieved irrespective of personal capabilities of the operators. Since this type is structured in a compact size with a light weight and is adapted to be driven with a battery, it permits measurements at any places. The measuring procedures with using type are simple and easy to handle for any operators. The measuring method is conformable to ASTM.
