About Leica Disto
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 our 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.
The Ingress Protection (IP) rating was developed by the European Committee for Electrotechnical Standardization (CENELEC) to create a standard of toughness.
Our most rugged laser distance meters, the X3 and X4 exceed the IP65 class rating with the rest of the line exceeding IP54.
So what does that mean, exactly?
IP65 First number (6)- Protection against solid objects
|0||No special protection|
|1||Protected against solid objects over 50 mm, e.g. accidental touch by a person’s hands.|
|2||Protected against solid objects over 12 mm, e.g. a person’s fingers.|
|3||Protected against solid objects over 2.5 mm (tools and wires).|
|4||Protected against solid objects over 1 mm (tools, wires, and small wires).|
|5||Protected against dust limited ingress (no harmful deposit).|
|Totally protected against dust.|
IP65 Second number (5) – Protection against liquids
|1||Protection against vertically falling drops of water e.g. condensation.|
|2||Protection against direct sprays of water up to 15° from the vertical.|
|3||Protected against direct sprays of water up to 60° from the vertical.|
|4||Protection against water sprayed from all directions – limited ingress permitted.|
|Protected against low pressure jets of water from all directions – limited ingress.|
|6||Protected against temporary flooding of water, e.g. for use on ship decks – limited ingress permitted.|
|7||Protected against the effect of immersion between 15 cm and 1 m.|
|8||Protects against long periods of immersion under pressure.|
3 Year Warranty Exchange Program
Leica Geosystems makes sure you can treat a Leica DISTO™ like tools without sacrificing accuracy.
For example, we know a Leica DISTO™ will bake on the dash at an Mount Isa job site or be left overnight in the ute in the middle of a Tasmanian winter. That’s why we make sure they have a storage temperature range of – 26°C to 70°C.
With that kind of toughness built in, it is rare for a Leica DISTO™ to have a problem, but in the unlikely event of a defect Leica Geosystems offers a two year exchange warranty. That can be extended to three years, for free if the device is registered within eight weeks of purchase.
