This 311D series gauge line is designed for process applications where 1 % accuracy and calibration via an adjustable pointer are desired to monitor important pressures accurately. This gauge has been specifically designed with higher-end process applications in mind and are used on any process systems as well as any commercial or industrial application where stainless steel wetted parts are needed. These gauges also have laminated safety glass lens required where chemical wash downs are common and/or safety requirements demand shatter resistant glass lens.
