✅ EXACT MEASUREMENT - The Risscard is perfect for the work of experts. You can measure cracks from 0.1 mm to 6.5 mm with pinpoint accuracy.
✅ RULER GRADUATION - On the front there is a 10 cm ruler, starting from 0 mm as a gauge, as well as a size comparison ruler in blue / white over a width of 10 cm.
✅ DOUBLE SIDED USE - Use is made by placing the cards over the crack to be measured. By comparing it with the appropriate line width, the crack width can be read off and documented.
✅ MADE IN GERMANY - With a thickness of 1.0 mm plastic, the ruler is very stable. It is therefore more stable than a credit card (0.76 mm) and is sure to remain a loyal companion for a long time.
✅FINE HANDY - The Risse ruler has a size of only 100 x 35 mm. This makes it easy and convenient to carry along with you. Whether in your wallet or in your briefcase.
