The high-pressure version is designed to measure bottle pressure and the amount of volume left in the bottle. The gauge is manufactured in accordance with Underwriters Laboratories Standard UL 404. The low-pressure version of the compressed gas gauge indicates downstream or regulated pressure. It is made in several ranges to allow the user to select the best possible range for the application. Both gauges are manufactured to the very highest of standards and made to cleanliness Level IV of ANSI B40.1-1980.
