The Leica DISTO™ X310 is the only laser distance meter to be dust-tight and protected against water jets – to IP 65. In addition, it passes drop tests of up to 2 m height. Thanks to the integrated tilt sensor, it can take indirect distance and height measurements absolutely precisely.

Robust housing
The sensitive measuring elements are protected by solid rubber parts. Proven in drop tests from up to 2 m height, the Leica DISTO™ X310 is therefore particularly resistant.

Protection class IP 65
The housing and keypad are specially sealed against water and dust. Cleaning under running water is also no problem.

Tilt sensor 360°
Thanks to the combination of distance and tilt measurements, you can determine the horizontal distance absolutely precisely and simply – even past obstructions. With the help of the tilt sensor, you can also determine indirect heights.

Smart Horizontal Mode™
If obstructions prevent you from taking direct distance measure-ments, you can use the Smart Horizontal Mode™ to determine the horizontal distance simply and absolutely precisely.

ISO Standard 16331-1 – The standard for laser distance meters
The range and accuracy of laser distance meters depend on light conditions and reflectivity of the measuring target. For Leica Geosystems it is important that the instruments not only perform under perfect laboratory conditions, but above all under the kind of everyday working conditions encountered on construction sites. This is why, working together with external experts, the company have developed a standard by which laser distance meters can be tested and compared with each other.

Features and Functions

Functions are icons with a blue background while features are white icons with red.

Smart Horizontal Mode Icon Smart Horizontal™ Mode

Smart Horizontal Mode

Use Smart Horizontal to determine the level horizontal distance to a target when you have to shoot over an obstacle. The onboard 360° tilt sensor provides an angle measurement so the software can do the math to figure out how much to subtract from the angled shot to get the actual horizontal distance.

Min / Max Function Icon Min / Max Function

Min / Max Function

In Min/Max mode, you "sweep" the laser point into a corner. The longest measurement is recorded. Very useful for accurate diagonal room or window/door measurements.

Area / Volume Icon Area / Volume

Area / Volume

In area mode, the DISTO determines the area of a rectangle or square in two shots.

Volume mode adds a third vertical shot to calculate volume.

Triangle / Room Icon Triangle / Room

Triangle / Room

The simple area function is great when a room is a square or rectangle, but what if you have to determine the area of a room that has more than four corners? That is where the triangle function comes in. Divide the room into imaginary triangles, take three shots for each and then add them up. The DISTO will also tell you circumfrence and the angle of the triangle.

Painter Function Icon Painter Function

Painter Function

When the DISTO is in area or volume mode, you can use the add / subtract function to total up the area of several surfaces, or subtract an area, like a door for example, from a measurement.

Pythagoras Function Icon Pythagoras Function

Two Point Pythagoras

Take indirect height and width measurements using the Pythagorean Theorem.

Three Point Pythagoras

The key is to make sure your second shot -- the "rectangular shot" -- is perpendicular to the point you are measuring, shown as the 90° angle in the images. The best way to ensure accuracy is to use a tripod and an adapter.

Height Tracking Profile Height Tracking

 

 

 

 

"Real time" height tracking for situations where you can hit a reflective target (like the ground) on the low end, but not at the top. Perfect for measuring the height of an overhead wire, for example.

Stake Out Function Icon Stake Out Function

Stake Out Function

The stake out function uses the continuous measurement mode to indicate where to place stakes along a stake-out line. Ideal for any situation where you need to place objects at a consistent interval. The display shows the distance to the next stake out point and the DISTO beeps as you approach it.

360° Tilt Sensor Icon 360° Tilt Sensor

Functions that need to know the angle of the DISTO when the shot is taken are enabled by a highly accurate 360° tilt sensor that determines the angle of the laser. These include Smart Horizontal and Height Tracking modes.

Add & Subtract Icon Intelligent Endpiece

Intelligent Endpiece

The endpiece is an integral part of the tool, connected to the circuit board.

In the closed position the DISTO knows to measure from its base.

Flip it open 90 degrees to align the base perfectly on an edge or corner.

Flip it out all the way and you can put this baby in a corner to accurately measure diagonals. Otherwise, the width of the base would prevent you from getting all the way into the corner, rendering the measurement inaccurate.

Add & Subtract Icon Add & Subtract

It's not always so simple as taking one shot to get the measurement you need. Sometimes its handy to add multiple shots together, or subtract a negative space from a measurement.

As you use the Add/Subtract function, the final result is displayed in the main line, and the last measurement taken is shown above.

Memory Stores 30 Displays Icon Memory stores 30 Displays

Store measurements and images with measurements associated with them.

Timer Icon Timer

Set a timer to delay a measurement the same way you would with the shutter on a digital camera.

IP65 Icon IP65

"IP" stands for Ingress Protection. 

The Ingress Protection (IP) rating was developed by the European Committee for Electrotechnical Standardization (CENELEC) to create a standard of toughness for electronic devices: Higher numbers mean more resistance to dust and water.

For more information on IP ratings, see the IP section on the Certification page.
