IS-Pro™ class I division 1 EPC is designed for pressure control in hazardous environments. It is suitable for both flowing and dead-ended applications in class I division, 1 or class I zone 0 settings, providing precise and consistent measurements along with rapid proportional control. This makes it an excellent choice for pilot pressure to dome-loaded pressure regulators or backpressure control in analyzers.
The IS-Pro™ is intrinsically safe and can be used in hazardous zones without an explosion-proof housing. It is certified for use in North America (CID1), Europe (ATEX zones 1 & 0), and has international certification (IECEx).
