Vertical & Horizontal Accuracy: ±0.75mm/5m Orthogonal Accuracy: 90°±30" Plumb Down Point Accuracy: ±1mm/5m Self-Leveling Range: Approx ±2.5° Working Distance: Approx radius 15m indoor, increasing to 60m+ with detector Emit Angle: >=120° Laser Wavelength: 635nm x 3 Laser diodes Laser Standard: Class II (<1MW) Working Temperature: -10°C ~ +50°C Power: DC4.5V ( 3 section of AA Alkaline batteries), rechargeable function and lithium battery optional. Operate Time: Approx 12 hours Weight: 1.3kg (with batteries) Color: Any color available as per color code provided. * With gravity pendulum and magnetic damp self-leveling, easy operation, highly trustiness.
* With laser diode wavelength 532nm for vertical and horizontal line, 650nm for plumb down point,
* It builds two vertical lines, one horizontal line and plumb down point * With fine adjustment for convenient working * With indoor & outdoor switch function * Have a wide leveling range. * Rotating fine adjustment mechanism and the limb 360° allow to find objects precisely.
* Laser level alarms by twinkle laser lines automatically and doesn't allow doing
