What are the differences between laser rangefinders and ultrasonic rangefinders?
1. In terms of accuracy, the measurement accuracy of ultrasonic rangefinders is at the centimeter level, while that of laser rangefinders is at the millimeter level;
2. In terms of measurement range, the measurement range of ultrasonic rangefinders is usually within 80 meters, while the measurement range of handheld laser rangefinders can reach up to 200 meters, and the measurement range of laser rangefinders can reach hundreds or even thousands of meters, even further (the measurement accuracy of laser rangefinders is usually 1 meter or tens of centimeters).
3. Ultrasonic rangefinders are prone to errors. As ultrasonic rangefinders emit sound waves and have the fan-shaped emission characteristics of sound waves, when there are many obstacles where sound waves pass through, the reflected sound waves are more, causing more interference and easy to report errors. However, laser rangefinders emit a very small beam of excitation light before returning, so as long as the beam can pass through, there is almost no interference.
4. The price of ultrasonic rangefinders ranges from tens to hundreds of yuan, while the price of laser rangefinders ranges from hundreds to thousands or tens of thousands of yuan, which varies greatly depending on accuracy and distance.
Therefore, laser rangefinders have long been applied to various industries in our daily lives, such as interior designers, surveyors, evaluators, on-site power measurement, firefighters, land planners, real estate developers, stage builders, factory and warehouse planning, exhibition builders, forestry workers, designers, fire safety, industrial transmission, traffic accident sites, crane drivers, surveying and software applications, Handheld laser rangefinders are commonly used in professional measurement fields such as data modeling.
