Is the Pressure Gauge 1000 bar EN 837 (S2), MGS 18, 63 mm, Male Thread suitable for use with corrosive liquids and aggressive media?

Pressure Gauge 1000 bar EN 837 (S2), MGS 18, 63 mm, Male Thread — suitable for use with corrosive liquids and aggressive media? Yes. The MGS 18 is explicitly designed for demanding and aggressive media: stainless-steel housing, mechanism, Bourdon tube and AISI 316L connection provide strong corrosion resistance. Silicone oil filling protects the movement from pulsation, vibration and corrosive atmospheres, and the polycarbonate window adds mechanical protection. Built to EN 837-1 in a safe S2 version with IP67 protection, it is intended for gases and low-viscosity, non-crystallizing liquids in chemical, petrochemical and other industrial environments. Operative medium temperature up to +65°C should be respected. For highly aggressive, crystallizing or higher-temperature media, verify chemical compatibility with AISI 316L and consider additional isolation (e.g., diaphragm seal) if needed.

Can the Pressure Gauge 1000 bar EN 837 (S2), MGS 18, 63 mm, Male Thread be used in outdoor installations exposed to heavy rain and dust while maintaining IP67 protection?

Yes. The Pressure Gauge 1000 bar EN 837 (S2), MGS 18, 63 mm, Male Thread is suitable for outdoor installations exposed to heavy rain and dust while maintaining IP67 protection. Its stainless-steel housing and AISI 316L connection provide corrosion resistance; the polycarbonate window adds mechanical strength; silicone oil filling prevents internal condensation and protects the movement from pulsation and vibration. With a rated IP67 enclosure and an operating ambient range of −40°C to +65°C, it is designed to remain dust-tight and withstand temporary immersion and heavy rain in typical outdoor industrial environments, provided installation follows manufacturer guidelines (correct sealing of the thread/connection and mounting orientation) and media/temperature limits (medium temperature up to +65°C) are respected.
