Accuracy with Leica Disto's
Certified for Accuracy
A laser distance meter is only as accurate as its measurement module. To be sure that a distance meter is accurate, you need to know that the actual module in the tool in your hand is accurate.
Other manufacturers drop modules in a chassis and ship them with a generic piece of paper that says “This module meets this spec”…but does it?
That kind of uncertainty would keep Leica engineers awake at night.
Every Leica DISTO™ module is tested before assembly and matched to a serial number. The tool is tested again after assembly. The specific variation within our spec for each unit is recorded on a Certification of Accuracy that is included in the box.
This process is managed by the same Quality Assurance team that ensures that our $50,000 Smart Station is accurate enough for the most demanding engineering challenges on Earth.
In theory, a laser distance meter will perform the way its maker says it will, but in practice many factors — like the ambient light conditions or the reflectivity of the target surface — impact range and accuracy.
When a manufacturer says a laser tool is accurate, does that mean it is accurate in the lab or in real working conditions? Different manufacturers had different answers to that question.
Without a standard, it was impossible to compare the range and accuracy between manufacturers on a level playing field.
That’s why Leica Geosystems engineers helped write the ISO 16331-1 Standard for Laser Distance Meter Range and Accuracy.
Now, before you buy any laser distance meter, you can check to see if it meets the ISO standard.
