Abstract: A laser-leveling device having a at least one radiation module and mounting module, where laser radiation sources and the prisms for developing planes from the laser beams are combined in the radiation module. The radiation module with housing contains a device for horizontal fine adjustment, an additional power supply with control, and an additional self-leveling support plate for receiving the laser radiation sources and prisms for developing the planes from the laser beams The mounting module with housing contains a self-leveling support plate, power supply with control, and a mount for securing to a tripod. The housing of the at least one radiation module and the housing of the mounting module are embodied such that the radiation module can be coupled to the mounting module, and it is possible to connect at least one additional radiation module.

Abstract: The invention relates to a laser distance meter with expanded functions, comprising a module for measuring distance, area and volume, wherein an optical axis of said module is fixed relative to a fastening point on a tripod and relative to a distance reference point, said meter also comprising a signal evaluation circuit, a microcomputer, a memory, a control panel, a screen and a battery. According to the invention, a module is provided for marking the reference axes using a pendulum and a laser fastened to the pendulum, said module, in addition to the module for measuring distance, area and volume, able to be connected for displaying the position of the axes.
