Curved/Circular/Arc Measurement Instrument Roller Distance Meter Laser & Roll Dual Mode Electronic Ruler Laser Distance Meter Laser Tape Measure

Curved/Circular/Arc Measurement Instrument
Features:
- Contact-type: Uses mechanical probes or rollers to roll along curved surfaces, recording trajectories and calculating parameters such as curvature radius and arc length (e.g., digital radius gauges).
- High precision: Contact-type instruments achieve micron-level accuracy, while non-contact-type instruments depend on sensor resolution.
- Portability: Handheld devices are suitable for on-site measurements, while fixed devices are used in laboratories.  

Laser Rangefinder  
By emitting a laser beam to the target surface, receiving the reflected light, and calculating the round-trip time of the light wave (Time-of-Flight, ToF) or phase difference, the distance is determined.  
Features:  
- Non-contact measurement: Avoids damage to the measured object.  
- High precision: Typically within ±1–2 millimeters, with a measurement range of tens to hundreds of meters.  
- Fast response: Displays data in real time, suitable for dynamic measurements.  

Application scenarios:  
- Industrial manufacturing (e.g., automotive curved sheet metal, turbine blade inspection).  
- Mold design, jewelry processing, and other small-scale curved surface measurements. 
- Curved surface verification for architectural domes and artistic sculptures.  

Features:  
1. Compact and portable, capable of multi-angle measurements.  
2. Digital display roller distance meter: cutting-edge technology for curved surfaces.
3. Data storage: View anytime, anywhere, conveniently and quickly.  
4. Type-C lithium battery direct charging: Built-in 240mAh high-density lithium battery provides long-lasting power support for work.  
5. Large LED display: Full-screen design with a high-definition LED display for clear and accurate readings.  
6. 100-meter ultra-long measurement range: High precision with a measurement range of 0-99.999 meters.
