Mini Compass
Highly sensitive mini compass for detecting magnetism. With this aid you have optimum security when testing magnetism on movement parts or complete movements.
Recommendation!
If a movement is slow or if it sporadically stops completely, then in most cases magnetism is the reason. We recommend checking the movements for magnetism and demagnetizing them with a demagnetizer if necessary.
Dimensions (Ø x H): 14 x 6.5 mm
