APPLICABILITY Measurement of the length and diameter of objects, excellent and accurate measuring tool of caliper do home and DIY measurements. Specification: Item Type: Electronic Digital Caliper Material: carbon fiber composites Purpose: Measurement of length and diameter of objects Accuracy: 0,1 mm/0,01 inch Resolution: ±0,2 mm/0,01 inch List of packages: 1 x Caliper Application of caliper: The caliper reader with nonius consists of two parts: the ruler body and the nonius body. When the movable measuring claw on the ruler frame matches the do fixed measuring claw on the ruler body, the engraved line “0” (nonius line 0 for short) is aligned with the engraved line “0” on the ruler body, and the distance between the measuring claws is 0 at that time. When measuring the ruler frame, move do of the specified position to the right. At this point, the distance between the moving measuring claw and the stationary measuring claw is the measured size, see schemat of the measurement.
