Intrinsically Safe Pressure Meters

IS-Pro™ intrinsically safe electronic pressure gauges

IS-Pro intrinsically safe pressure meters provide high performance pressure measurement for flowing processes in continuously explosive gas atmosphere hazardous locations. Their IP66 rated cases help eliminate the need for a heavyweight enclosure. IS‑Pro pressure meters have ATEX, IECEx, and North American CID1 Certificates for use in continuously explosive gas atmosphere hazardous locations.
