We've defined a new benchmark! ISO Standard 16331-1
The standard for laser distance meters

ISO Standard 16331-1

Working together with external experts, Leica have developed a standard by which laser distance meters can be tested and compared with each other.

The new ISO Standard 16331-1, to which Leica Geosystems has made a significant contribution, defines in detail how information concerning accuracy and range must be presented and describes the necessary measuring procedures. This renders specifications of laser distance meters capable of being tested by independent institutions, thus making direct comparisons possible.

The ISO Standard 16331-1 takes the following measuring conditions into account:

Measurement under favorable conditions:
(conditions which often apply for interior use)
Measurement under unfavorable conditions:
(conditions which often apply for exterior use)
Other measuring conditions:
(can also be specified, for example)
  1. Weak ambient light (3 klux)
  2. Measuring to white painted wall
  3. Room temperature
  1. Bright sunshine (30 klux)
  2. Measuring to white painted wall
  3. Total operating temperature range
  1. Measuring to a defined target plate
  2. Measuring to unfavorable measuring points with strong or weak reflectivity (metal surface or wet concrete)

A customer who purchases a laser distance meter which conforms to the ISO standard can arrive at reliable conclusions with respect to the maximum range and accuracy achievable under defined measuring conditions. This is crucial for assessing the advantages for everyday use on the construction site.
