LASER distance meters

Industrial LASER distance meters are used for distance measurement from a few millimeters up to a few kilometres.

The distance measure represents aconsolidated application for laser technology.

Industrial LASER distance meters use LASER light (pulsed or modulated) to measure distances, heights, lengths, levels and positions without any contact with the object to be measured.

Industrial LASER distance meters allow single accurate measurements to the millimeter and measuring ranges up to several hundred meters.

Typical applications are the non-contact distance and position measurement or applications for controlling the position of large structures (cranes, gantries, boats, vehicles, trains, wagons, dams, bridges and heavy infrastructures).

Non-contact measurement with LASER distance meters is also widely used for level measurement of granules, powders and liquids at high density or in applications where the operator cannot access the measurement area (high temperatures, confined spaces, presence of vapors or dangerous contaminants).
