Efficient laser types: TRL-440 ROTARY LASER offers two laser types：
TRL-440 HVR Rotary Laser and TRL-440 HVG Rotary Laser.
TRL-440 HVR Rotary Laser: green laser (515nm-30mw) and TRL-440 HVG Rotary Laser : red laser (635nm-10mw), ensuring excellent visibility in all lighting conditions.
Electronic level adjustment: Equipped with an advanced electronic level adjustment system (gyroscope two independent electronic sensors), the level adjustment range of TRL-440 ROTARY LASER can reach ±5°, ensuring precise measurement.
Wide working range: TRL-440 Rotary Laser With LP500, the working radius can reach 500 meters; with LP700, the working radius can reach 400 meters, suitable for various large-scale construction projects.
Fast rotation function: TRL-440 Rotary Laser Supports laser rotation speeds of 0/150/300/600 rpm, combined with silent belt drive to meet the needs of different scenarios.
Intelligent remote control operation: Slope operation can be performed through the RC200 remote control, and the remote control distance can reach 300 meters, which greatly improves the flexibility and convenience of operation.
