What distinguishes an ultrasonic rangefinder from a laser rangefinder?
1. In terms of accuracy, the measurement accuracy of the ultrasonic rangefinder is at the centimeter level, and the measurement accuracy of the laser rangefinder is at the millimeter level;
2. In terms of measurement range, the measurement range of the ultrasonic rangefinder is usually within 80 meters, while the measurement range of the handheld laser rangefinder can reach up to 200 meters, and the measurement range of the laser rangefinder telescope can reach hundreds of kilometers. Even farther (the measurement accuracy of laser ranging telescopes is usually 1 meter or tens of centimeters).
3. The ultrasonic range finder is easy to report errors. Since the ultrasonic range finder emits sound waves and has the fan-shaped emission characteristics of sound waves, when there are many obstacles where the sound waves pass, there will be more reflected sound waves, more interference, and error reporting. The laser rangefinder is a very small beam of laser light that is emitted and then returned, so as long as the beam can pass through, there is almost no interference.
4. The price of an ultrasonic rangefinder ranges from tens of yuan to several hundred yuan, and the price of a laser rangefinder ranges from a few hundred yuan to several thousand or tens of thousands of yuan, depending on the accuracy and distance.
Therefore, laser range finders have long been applied to various industries in our lives, such as: interior designers, surveyors, appraisers, power site surveys, firefighters, land planners, real estate developers, stage construction, factory and warehouse planning, Exhibition builders, forestry workers, design, fire safety, industrial transmission, traffic accident scenes, crane drivers, surveying and mapping and software application providers, data modeling and other professional measurement fields will use handheld laser rangefinders.
