A8921G H V High Precision Green Rotary Laser

A8921G Product Features
1.Ultra-High Precision & Electronic Self-Leveling
->±1mm High Accuracy: Horizontal and vertical accuracy strictly controlled within ±1mm at 30m, ensuring precise reference points.
->Smart Electronic Self-Leveling: Advanced electronic leveling with ±5° compensation range. Faster response and locking than mechanical leveling, reducing human error for strict standards.
2.High-Visibility Green Laser Technology
->520nm Wavelength: Utilizes 520nm green laser, the peak sensitivity of the human eye, making it 4-6 times brighter than standard red beams.
->Superior Visibility: Ensures clear beam visibility in bright light or over long distances, significantly reducing eye fatigue and boosting measurement efficiency.
3.Multi-Mode & Slope Function
->Dual-Mode Switching: Supports Horizontal Mode (horizontal plane + upper/lower plumb points) and Vertical Mode (vertical plane + horizontal line) for complex spatial measurements.
->Professional Slope Setting: Built-in slope function for easy inclination angle setting, solving grading challenges for drainage ditches and ramps.
4.1000m Working Range & Remote Control
->Large-Scale Coverage: Designed for large projects with powerful signal transmission. Outdoor working radius up to 500m (1000m diameter) with high-sensitivity digital receiver.
->25m Remote Control: Supports 25m remote operation, eliminating frequent trips between instrument and measurement points for efficient solo work.
5.Smart Multi-Function & Impact Detection
->Adjustable Settings: 4-level zone scanning (15°/50°/100°/220°) and 4-level rotation speed (0/150/300/600rpm) for different lighting and construction environments.
->Bi-Directional Rotation: Supports left/right rotation for flexible operation.
->Impact Detection Protection: Smart "electronic eye" automatically alarms and stops operation upon accidental bump or displacement, preventing erroneous data.
6.Military-Grade Protection
->IP66 Top-Tier Protection: IP66 rated for complete dust protection and resistance to powerful water jets.
->All-Weather Operation: Stable operation in harsh outdoor environments including heavy rain and dust storms, with superior durability.
7.Long Battery Life & Convenient Power Supply
->Dual Power Supply System:Replaceable 2x18650 lithium battery pack with Type-C and power adapter charging support.
->Ultra-Long Runtime: 23-25 hours of continuous operation on a single charge for all-day high-intensity work.
8.Smart User-Centric Design
->Status at a Glance: Battery pack with LED power indicator for real-time battery monitoring.
->Dual-Screen Digital Receiver: Dual-screen LCD receiver for clear, intuitive readings from any angle, improving solo work efficiency.
