Industrial 4025C Capsuhelic Differential Pressure Gauge from Dwyer Instruments is a 0–25 in. w.c. differential pressure indicator in the Series 4000 Capsuhelic line, designed to provide fast, direct indication of small pressure differences. It uses 1/4 in. FNPT process connections for easy installation in ductwork, filtration paths, or other low-differential applications. The 4025C designation denotes the 0–25 in. w.c. range within the Capsuhelic family, delivering reliable mechanical measurement without electrical power. This model is specified for ambient temperatures from 20 to 200°F (about -6.7 to 93.3°C).
