Model 124 ”Filter Minder” DP Gauge
Mid-West Instrument’s Model 124 is a versatile piston-type differential pressure gauge designed for applications that require large differential pressure ranges. It has differential pressure ranges of 0-0.35 to 0-27.6 bar, as well as safe working pressures up to 10,000 PSI. This gauge’s full-scale accuracy is ±3/2/3%, making it ideal for precision monitoring in demanding applications. The Model 124 has a sturdy aluminium body, 316/316L stainless steel wetted parts, and a shatter-resistant lens for durability. It also provides NEMA 4X weather protection and is RoHS compliant.
