Stainless steel pressure gauges can be used to measure pressure, and when calibrated with high-precision transmission mechanisms, they ensure accurate indication precision. This dataset includes major raw and auxiliary materials used in the production process, but infrastructure such as production equipment and factory construction is not included within the dataset boundaries. The life cycle inventory is compiled from data from multiple sources. The manufacturing process of stainless steel pressure gauges includes assembly, rough adjustment, aging, fine adjustment, inspection, packaging, and warehousing.
