SR33/34 – Discontinued – Replaced by SR74/75

Magnescale’s proven Magnescale® is enhanced by several new technologies. The scale boasts superior speed and accuracy in addition to its conventional high level of reliability in a hostile enviroment and easy of use. Despite being a shield-type scale, it offers a high response speed of 150 m/min.
