APL203 Automatic Self-leveling Laser Cross Line

APL203 projects 2 powerful laser lines (One horizontal and one plumb line).  With convenient operation, complete functions and lower requirements for working conditions, APL203 can be installed on tripods or lift poles and will locate the horizontal and plumb direction anywhere on the metope!

Lightweight design that’s easy to carry but very powerful!

Ⅰ Instrument Operational Principle & Application

APL203 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 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.
