E420 Setting a new standard for entry level systems

The Easy-Laser® E420 sets a new standard in entry level laser systems for shaft alignment. Wireless measuring units, a large 5.7” colour display and an IP65-rated design that withstands harsh environments. These are the features you would normally only find in more expensive systems!

Compact wireless technology

The measuring units are incredibly compact featuring Bluetooth® Wireless technology, an integrated rechargeable battery and large 20 mm TruePSD detectors. This means that they are easy to install on most types of machines, even where there is limited space. The wireless technology gives you full freedom of movement around the machine that is to be aligned.
Programs for alignment of both horizontal and vertical machines are included. Added to that are functions for soft foot control, thermal growth compensation and tolerance control.

Easy to use

The measurement system is very easy to use. Pre-mounted units make it easy to install on the machine and the programs guide you step-by-step through the process. Start with the measuring units positioned anywhere on the shaft, recording three readings with as little as 20° of rotation between readings. Then adjust the machine with the live values, and save the measurements in the display unit memory. You can also transfer the results to the database EasyLink ™ program (included) for PC.
Easy-Laser® E420 has everything an entry level system should have, and more. Simply put, Easy-Laser® sets a new standard for measuring.
