Tell Tale Crack Meters EXB0008F

Tell-Tales consist of two plates which overlap for part of their length. One plate is calibrated in millimeters and the overlapping plate is transparent and marked with a hairline cursor. As the crack width opens or closes, one plate moves relative
to the other. The relationship of the cursor to the scale represents the amount of movement occurring. Range ±20 mm – Resolution 1 mm. The telltales are fixed with screws and adhesive across the crack to be monitored.
