The new SOLA precision spirit level has been specifically designed for craftsmen, where highest accuracy determines the quality of the work results. This precision is achieved by the use of high-strength aluminum in an extremely stable profile shape and the high-sensitive SOLA Focus vials, which display even the smallest deviation contrasting and clearly visible. The U-shaped high-visibility vials allow best readability in all possible measuring positions. In order to improve the haptic adaptation and allow convenient working plastic handle inserts had been applied to the spirit level.
