D550 Extreme Laser Shaft Alignment Tool

Extremely durable and ATEX / Ex approved
Easy-Laser® Extreme™ is one of the toughest and most robust measurement and alignment systems on the market for work in potentially explosive environments. Easy-Laser® Extreme™ is intrinsically safe and complies with the latest ATEX standards for work in such environments.

With Easy-Laser® Extreme™ we have gone one step further. The entire construction is extremely durable with regard to external influences, not just shockproof, but also resistant to corrosion and leaks. This is because we know that measurement systems are all too often used in environments that are anything but clean and dry. This could involve anything from water to oil or solvents. The measurement system is therefore naturally IP66 and IP67 approved. In other words, system D550 is not just for those who need an Ex-approved system, but also for those who want a little extra from their tools. Viewed as a whole, with its robust construction, its software and its generous warranty period, you get a measurement and alignment system that is extremely hard to beat!
