• Not only the wetted part (Screw Portion, Bourdon Pipe), but also the case, scale plate, needle, screw, and all other parts (Excluding glass and terashi) are made of stainless steel, giving it excellent corrosion resistance.
• In particular, even in a corrosive atmosphere, not only the case but also the scale plate, needle, etc. can be kept in a clean condition without rusting.
