Feature:1. [IP54 Water Proof] The automatic level features sturdy aluminum alloy body with IP54 water proof and dust proof rating, suitable for harsh environments.2. [Auto Leveling] Magnetic damping compensator offers large compensation space and stable structure, ensures precise and stable measurements.3. [High Definition Eyepiece] The crosshair can be clearly observed by rotating the eyepiece, supporting crosshair calibration to calibrate screws.4. [Bubble Level] The level gauge is equipped with a bubble observer, which can assist in correcting the level. The bubble should be in the center, otherwise it needs to be calibrated.5. [Clear Scale Disc] The auto level features a clear scale disc, allowing for 360 degree fine adjustment and accurate positioning for various needs.6. [Versatile Applications] Ideal for use in construction engineering surveys, deformation monitoring, mining surveys, road surveys, bridge and tunnel surveys, and more.Specification:Item Type: Automatic LevelMaterial: Aluminum alloyCompensator Type: Magnetic dampingDeviation Per 1km Round Trip: 1.5mmMagnification: 32XImaging: Positive imageObjective Aperture: 30mmField Angle: 120 minute of arcShortest Sighting Distance: 0.5MMultiplication and Addition Constant: 100, 0Compensator Working Range: 15 minute of arcLeveling accuracy: 0.4 angle of secondAccuracy of Circular Bubble: 8 minute of arc / 2mmRotating Base: 360 degrees or 400 degrees optionalBattery: 3 x AAA batteries (not included)Laser Beam Coaxiality Error: 5 angle of secondLaser Pointer Range: 200MLaser Power: 5MVIP Rating: IP54.Package List:1 x Automatic Level1 x Plumb Line2 x Wrench1 x User Manual1 x Storage Box
