Information about the device

Device description
The laser distance measuring device BD11 is used to determine distances, areas and volumes in interior spaces. Indirect measurements are carried out employing the Pythagoras function. The multi-line, illuminated display indicates the determined values.Owing to the dust- and splash-proof housing (IP54), the device is also suited for use on construction sites.

Measuring distance
The range of the device can be gathered from the Technical data chapter. Under certain conditions – e.g. at night, in twilight or when the target is hidden in the shade – greater distances are possible even without target plate. During the day use a target plate to increase the distance for poorly reflecting targets.

Target surfaces
There might be measurement errors when the laser encounters colourless liquids (e.g. water), dust-free glass, styrofoam or other semi-permeable materials. The measurement result may also be falsified if the laser encounters a high- gloss surface and is deflected by it. Non-glossy, non-reflective or dark surfaces can extend the measurement duration.
