What is a steel tape measure? What are they used for?
A steel tape measure is also called a box rule. It is an ordinary measuring tool for measuring length. According to the different structure of its tape box, the tape measure is divided into four kinds of self-rolling tape measure, brake type tape measure, shake the tape box type tape measure and shake the tape frame type tape measure. Self-rolling tape measure and braking tape measure are mostly below 5m tape measure; the nominal length of rocking tape measure and rocking tape measure is more than 5m. Steel tape measure category steel tape measure nominal length: for the steel tape measure below 10rn to take o. 5 integer times; for more than 10m steel tape measure, to take 5 integer times. Tape measure specifications are Im, 2m, 3m, 3.5m, 5m, 10rn, 15m, 20m, 30m, 50m, 60m, 70m, 80m, 100m, etc.. Steel tape measure can be used to roughly measure the length, width, height, thickness and other dimensions of large workpieces, and can also be applied in geodesic measurement.

Common distance measurement methods include tape measure and photoelectric distance measurement. Tape measure is to use a tape measure that can be rolled up / test big / along the ground measurement, belong to direct distance measurement. Photoelectric distance measurement is to use the instrument to transmit and receive modulated light waves between two points to determine the distance according to its propagation speed and time, which is electrophysical distance measurement. Optical distance measurement belongs to indirect distance measurement.
