Very Low Pressure Differential Pressure Gauge

Differential Pressure Gauges (Magnetic Capsule Type) are precision instruments designed for accurate measurement of low differential pressures in air and compatible gases. With a large 4.5″ dial for clear visibility, these gauges are ideal for monitoring clean rooms, HVAC systems, and filter conditions. The magnetic coupling mechanism ensures reliable and frictionless operation without direct contact between sensing and indicating elements.
