S-700: Compact Polariscope
For the visual inspection of stress in glass and plastic objects such as ampoules, vials or thermoformed packaging, for example.
In clear and translucent polymers, the strain appears as a colourful fringe pattern.
In production, this simple test can quickly identify defective parts and alert operators to adjust process parameters.
The procedure is non-destructive.
Dimensions: 21x17x23cm
Field of view: 10x10cm
Maximum sample height: 24.5cm
Sharples S-66: Senarcom Strain Viewer
Update coming soon!
Accurate assessment of stresses or strains in glass and plastics products is an essential requirement of the setting of standards for product manufacture and quality control.
The Sharples Senarcom Strain Viewer enables qualitative and quantitative assessments to be made of the stresses and strains in transparent bottles, precision glassware and other glass or plastics products. The stress or strain magnitudes in the component under examination can be accurately measured using the Senarmont method of compensation.
Sharples S-67: Edge Stress Meter
Update coming soon!
The Sharples Edge Stress Meter has been developed to offer a convenient method of measuring the edge stresses in glass sheets.
Amongst the applications are the measurements of edge stresses in :
1. Laminated glass sheets; e.g. Wind shields, Safety windows.
2. Toughened or tempered glass.
3. Heat-Strengthened glass.
The Sharples Edge Stress Meter is a portable instrument which allows quantitative measurements of stresses at the edges of glass sheets by employing the Senarmont (or Friedel) method of compensation.
A transparent scale is provided in the optical field which allows measurements to be made at distances of up to 50mm from the edges of the sheets. Measurements away from the edges are only possible where the principal stresses are parallel and perpendicular in direction to the edges of the ribbon.
The standard model accommodates sheets of up to 25mm in thickness.
