2 axis PSD
The PSD (Position Sensing Device) which is built-in to the detector unit can determine the position in either 1 or 2 dimensions (axes). Call it X/Y, or Horizontal/Vertical if you want. Depending on application, a 2 axis systems will obviously give you more alignment possibilities. This system comes with a 2 axis PSD.

5 Programs
Easy-Laser® measurement and alignment systems comes with a wide range of application programs (apps). What you can measure is always a combination of apps, lasers, detectors and brackets. This system has 5 apps included. Learn more on Features tab.

20m/66' distance
The different Easy-Laser® laser transmitters are designed for optimum measurement result. Therefore they have different maximum measurement range. The range is also depending on the detector used.
This system (or transmitter) will allow you to measure at a range of 20m/66'.

The IP (Ingress Protection) rating system determines the level of protection against solid objects and liquids for a device. The larger the value of each digit, the greater the protection. IP66 - Ingress of solid objects: Totally protected against dust ingress. Ingress of liquids: Protected against high pressure water jets from any direction. Limited ingress permitted. 3 minutes, 100 l/min., 100 kPa water pressure from 3 m distance.

The IP (Ingress Protection) rating system determines the level of protection against solid objects and liquids for a device. The larger the value of each digit, the greater the protection. IP67 - Ingress of solid objects: Totally protected against dust ingress. Ingress of liquids: Protected against short periods of immersion in water. 30 minutes, 1 m.

Easy-Laser® XT770 is the most powerful of our Generation XT alignment systems. The 360° Live feature gives you even more possibilities to perform advanced adjustments. With XT770 you can carry out the following:

  • Align the machine
  • Check base twist
  • Check bearing play
  • Check soft foot
  • Measure machine movement over time
  • Document and share the results

The complete alignment system

With Easy-Laser XT770 you can perform shaft alignment of horizontal and vertically/flange mounted machines, but also align machine trains, measure twist of foundation, soft foot, bearing clearance, and more. The EasyTrend program allows you to keep track of machine movement over time. That is useful when checking for thermal expansion and pipe strain issues for example.

2 axis PSDs (position sensitive detectors) permit adjustment of your machine both vertically and horizontally at the same time, with measuring units in any position. We call it 360° Live adjustment. With the XT770 you have a choice of several different measurement methods, e.g. continuous sweep and multipoint. This gives you the flexibility you need to achieve the perfect measurement result.

Easy-Laser XT measuring units and display unit are shockproof and rated both IP66 and IP67 water and dust proof. Along with long operating times, this guarantees you will be able to take on and finish even the toughest jobs. 


Use the rugged Easy-Laser XT11 display unit, or install the free XT Alignment app on your iOS or Android device*. The intuitive user interface guides you through the measurement process.

Unique documentation possibilities 

The XT11 display unit has a 13MP camera. You can also get the XT11 display unit with a built-in IR camera.** This means you can add a thermal image of the machine before and after alignment. You can easily create and share a PDF report containing all measurement data and images.

Geometric measurements kit

With this kit added to your XT770, using the Values program, you will be able to take flatness and straightness measurements with the highest reliability and precision. The kit includes the very versatile and long proven laser transmitter D22 plus geo brackets.
