Selecting the correct technology depends on the required precision, distance, and environment. For high-precision engineering, Digital Calipers and Micrometers are essential, offering accuracy up to 0.001mm. For long-distance construction, Laser Distance Meters are preferred due to their ability to measure up to 200 meters with a margin of error of only ±1.5mm. If you are measuring moving objects in a production line, look for Encoder-based Wheel Meters or Non-contact Laser Doppler Velocimeters to ensure continuous data without surface damage.
