Description
Dwyer Magnehelic 2000 Differential Pressure Gauge 0-2" W10VJB 15 PSIG
The Dwyer Magnehelic W10VJB is a low-differential pressure gauge from Dwyer Instruments' well-known Magnehelic 2000 Series. It measures differential air pressure across a 0–2 inch water column (W.C.) range using Dwyer's magnetic reluctance mechanism, which delivers a smooth, accurate pointer response without the friction or stiction common in mechanical diaphragm designs. The dial face is clearly marked in inches of water and reads from 0 to 2 in fine increments, with a front-panel zero adjustment screw for field recalibration.

Applications
Dwyer Magnehelic gauges are standard instruments in HVAC and building automation systems, where they are used to monitor filter loading, measure duct static pressure, verify air flow across coils and dampers, and monitor pressure differentials in cleanrooms and controlled environments. The 0–2" W.C. range of this unit is particularly suited to low-velocity air systems and filter bank monitoring, where a small differential pressure reading indicates a clean filter and a rising reading signals time for replacement. These gauges are also used in industrial process monitoring wherever a low, visual differential pressure indication is needed without the need for a powered transmitter. The Magnehelic 2000 Series has been a widely used benchmark instrument in this application space for decades and remains in active use in facilities worldwide.
This Dwyer Magnehelic W10VJB differential pressure gauge has been inspected and appears to be in good used condition. The dial face is clean and legible, the pointer is intact, and the front zero adjustment screw is present. The housing shows light surface wear consistent with normal use. The unit was pulled from a working environment where it was previously in service. Please review our photos and contact us with any questions.
