The use of high-quality stainless steel materials and the robust design are geared to applications in the chemical and process engineering industries. Thus the instrument is suitable for liquid and gaseous media, also in aggressive environments. The low-temperature version POLARgauge® allows operation with ambient temperatures down to -70 °C [-94 °F]. Casings with safety level “S3” are fitted with a non-splintering window, a solid baffle wall between measuring system and dial and a blow-out back. In the event of a failure, the operator s protected at the front side, as media or components can only be ejected via the back of the case.
