Easy-Laser E920

GeometricEasy-Laser® E920 is a complete system in itself, with laser transmitter, detector and display unit. But it is also an excellent starting point for creating a measurement system that suits your specific needs and requirements, because all the measurement programs are included as standard!​ Add extra laser transmitters, measuring units and brackets as well as other accessories from the wide Easy-Laser range. Now or in the future.


Measurement system for all types of geometric measurement

Easy-Laser® E920 can be used to carry out all the most common geometric measurements; straightness, flatness, squareness, plumb, and level. Measurement is quick and precise.

Displayed resolution is 0.001 mm [0.05 mils]. The laser transmitter is our well known big seller, the D22 with leveling table, strong magnetic feet, and a range of up to 40 m. The transmitter's laser beam can be compared to an absolutely straight and weightless ruler, that is to say, a perfect starting point for precision measurement. The swiveling laser head gives a laser plane parallel to the measured object and can also angle the laser beam 90° to the sweep for squareness measurement.

The display unit has a large and clear 5.7” color screen. The programs guide you step-by-step through the measuring process, which makes it easy even for inexperienced users. The system can provide full documentation, with the direct generation of PDF reports and database programs for PC, for example. The detector transfers the measurement data to the display unit wirelessly or by cable if required. The advantages of wireless are especially clear on mechanical constructions and objects where cables can snag or get in the way.

The most common method is to fix the laser transmitter to the measurement object using the mounting magnets or mounting it on a tripod (accessory) to one side. A pin is also provided to secure the laser transmitter to a machine spindle or equivalent, for instance, to check straightness and spindle alignment.
