A handheld speedometer is a portable, handheld device used to quickly measure the instantaneous speed of moving objects.

Core Working Principle: Mainstream models employ radar or laser technology, emitting electromagnetic waves or laser beams and calculating speed by receiving changes in the frequency or time difference of the reflected signals.

Some simplified models are based on photoelectric sensing, suitable for short-range, low-precision scenarios.

Main Application Scenarios:

Traffic Enforcement: Used by traffic police to detect speeding vehicles on-site; a common enforcement tool.

Sports: Used to measure the speed of ball sports, track and field athletes, etc.

Industry/Scientific Research: Used to measure the instantaneous speed of mechanical parts and experimental objects over short distances.

Key Features:

High Portability: Small size and lightweight; requires no fixed installation and can be used anytime, anywhere.

Fast Response: Outputs measurement results quickly, suitable for dynamic detection.

Significant Accuracy Differences: Laser models offer higher accuracy (typically centimeter-level error); radar models are slightly more susceptible to environmental interference.
