NES-T Automatic Edge Stress Meter

Used for:

measuring edge stress in glass.

Conforms to:

ASTM C 1279-13

Principle of operation:

The device is positioned so that the edge of the glass enters the measurement slot. The NES-T sits on top of the surface of the glass.

This ensures proper alignment each time.

Option: positioning blocs are available for difficult geometries.

At the push of a button on the device, the measurement is done in seconds and all data can be found on the PC software ready to be exported, saved or to be further analyzed.
