Pressure & Differential Pressure Gauges

Magnehelic® and digital differential pressure gauges, and industrial and process pressure gauges.

Differential pressure gauges show at a glance the pressure across filters, fans and coils, and between rooms that must stay positive or negative. The Magnehelic® has long been the standard for low differential pressure in HVAC and cleanrooms, alongside the compact Minihelic® and digital models with alarm and control outputs. For process lines we also supply stainless steel, liquid-filled and contractor’s pressure gauges, plus gauge siphons for steam service.
