The universal industrial pressure gauge FM 633 with a 63 mm dial and rear connection is a reliable measuring instrument designed in compliance with EN 837-1 standards, offering durability and precision in demanding industrial environments. Its robust AISI 304 stainless steel housing with glycerin filling ensures excellent resistance to shocks, vibrations, humidity, and sudden pressure surges, while also protecting internal components from condensation and corrosion. The glycerin filling stabilizes pointer movement, reduces wear of moving parts, and guarantees consistent readings even under pulsating pressure conditions. Ideal for monitoring low-viscosity liquids, vapors, and gases that do not crystallize or corrode copper alloys, this gauge provides dependable performance across a wide range of applications. With an accuracy class of 1.6, a rear GZ 1/4″ BSP connection, and a durable plexiglass window, it combines precision with long-lasting reliability. Suitable for ambient temperatures from -40°C to +65°C and media up to +60°C, the FM 633 is the perfect choice for industries seeking a compact, efficient, and robust solution for everyday pressure measurement tasks.
