These are the very best large diameter (58 mm) dial indicators available. The craftsmanship and accuracy of these Swiss-made gages are superior to all others, but you will be paying a premium for this quality. Repair service is still available from Long Island Indicator Service for most models.
Water proof models have rubber seals and gaskets, plus a rubber bellows at the end of the spindle. These indicators come with flat backs. If you need a lug back, it will have to be ordered separately. See page 61 for details on lug backs.
These models are only rarely in stock in the U.S. and long delivery has to be expected. Sorry, we can not respond to inquiries from countries outside the U.S. at this time.
