Solartron Metrology, the world leader in linear measurement innovation, has now added another high performance sensor to it's line-up. Orbit® LTH is a Laser Triangulation unit for higher precision measurements, with 0.02% F.S. reading over 2 or 10mm measurement ranges. With the 2mm stroke, that means accuracy up to +/- 0.4 μm!
