APL304 Automatic Self-leveling Laser Cross LineThe APL304 provides cross laser lines projected in the positive direction coupled with a 90 degree vertical laser line on the side. Making perfect accuracy very easy to obtain! The super bright lasers make the visuals easy to see and provide confidence in the work to be performed! Ⅰ Instrument Operational Principle & Application APL304 Cross Line is a new type of integral instrument combined of optical, mechanical and electrical functions. It adopts laser diode of 635nm, can project visible red horizontal and plumb beam on the front wall, and can project plumb beam (it crosses 90° with front plumb beam) on the left wall. With the automatic compensator installed within the instrument, it automatically keeps the projected laser lines horizontal (or plumb) position. The instrument can be used for the purposes of indoor decoration, ceiling hanging, door and window installation, vertical wall partition, tube line laying and architectural constructions, etc. II Specifications Wave length | 635nm red laser | Laser diode power | <1mw | Line width | <3mm (Within 5 m) | Visible laser working range (radius) | 10m | Self-leveling range | ±5º | Leveling time | <3sec | Cross line accuracy | ±1.5′ | Front line accuracy | ±1′ | Left line accuracy | ±2′ | Refraction angle | >90º | Power sources | 3 pcs 5AA alkaline battery | | 10 hours | | -10℃~+40℃ | | 60mm×98.5mm×120mm | | 0.5Kgs | | 5/8 inch |
