The MASTER-50/MASTER-90 laser goniometer is an upgraded version of the previous MASTER model, featuring a redesigned appearance and enhanced structural solutions. In the new version, the laser and power board are integrated into a single rigid ring structure, eliminating the need for wired connections.
The key feature of the new version is the interchangeable scales, which allow for the measurement of blades with varying widths. The MASTER-50 and MASTER-90 models share a common base platform, ensuring functional similarity.
The number in the model name indicates the maximum blade width: 54 mm for the MASTER-50 and 87 mm for the MASTER-90. If you purchase the MASTER-50 model but later need to measure wider blades, there is no need to buy a new goniometer. Simply acquire the appropriate scale and replace it yourself. This process is very straightforward: the scale is secured with two M3 screws and fits perfectly into place thanks to guiding elements.
This design makes it possible to manufacture virtually any scale to meet specific requirements, making the goniometer a versatile tool for a wide range of applications.
ETA of the MASTER-90 model and the scale upgrade – Feb 2025.
