No oxide --- The wet part, totally made of fluorine-contained resin (PTFE), is highly resistant to the atmosphere and the chemicals in use. It produces no oxide.
・No specimen contamination --- Since the bellows pressure part has no trapped liquid or sealed liquid leaks, the liquid being measured is not contaminated by the pressure liquid even in an operation trouble.
・Hard casing --- The hard vinyl chloride case protects the gauge from adverse ambient conditions.
