IS-Pro class I division 1 pressure gauges are designed for measuring pressure in processes within hazardous environments, including CID1 and class I zone 0. This intrinsically safe pressure meter can safely be installed where explosive gases are continuously present, without needing an explosion-proof housing.
It is equipped with an IP66-rated enclosure, making it suitable for installation with analyzer shelters, well sites, and shaded outdoor areas. The backlit display facilitates rapid onsite verification, while digital or serial communication options enable seamless integration into the plant's automation system.
