- It is a long stroke dial gauge with φ57mm outer diameter of the outer frame. Since the outer frame and the giant board are integrated, the O -ring is incorporated, so there is no invasion of water or oil from the front. Stem spindle is stainless steel steel.It has a high strength that can withstand hard use. I am using a carbide product measuring child. Large gears use stainless steels with less wear and deformation. The outer frame giant plate is a test indicator, which has a proven track record, and has a reflection suppression, to improve visibility. Strength improvement by the cap integrated type.It is a product that can be used for "recovery service" that can be quickly and easy on the Internet to request or receive existing products.For more information, please check the re -calibration service category.
