The Dwyer Magnehelic 2004C differential pressure gauge delivers a 0–4 in. water column measurement range with 1/8 in. NPTF connections and a 15 PSIG rating. This model is part of Dwyer Instruments' Magnehelic line, offering a readable dial that translates differential pressure into a simple visual indication for on-site monitoring. Designed for compact, low-range differential pressure sensing, it provides a reliable option when tracking small pressure differences in space-constrained installations.
