Gauge Length Marking Tool for Laser Extensometers
Marking Tool for 10, 20, 25, 50mm or 1/2", 1", 2" Gauge Lengths
The Gauge Length Marking Tool is used for depositing retro-reflective tape onto ASTM samples. The tape is highly visible to laser extensometers which are used for non-contact strain measurement during tensile testing.
A few punch designs are available including either a 2 or 4mm circular dot, or a line which is 1x3.8mm or 2x8mm. The gauge length is adjustable, and there are two versions of the tool, one for imperial units and the other for metric.
An add-on tape reel holder is also available for higher volume manufacturing environments where many samples must be marked quickly. Automatic marking machines, based on an adjustable timer, are also available.
Universal Grip also retro-reflective tape from premium adhesive manufacturer Scotch (3M). the tape and tape reel are ready to mark samples, for a complete, out-of-the-box solution.
