The industry standard in indicating low air or gas pressures of positive, negative, or differential pressures
Large, easy-to-read 4" (102 mm) dial.
The gauge's motion is damped with high-viscosity silicone fluid.
The zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover.
O-ring seal provides pressure tightness.
Rugged design resists shock, vibration, and overpressure.
The helix is precision-made from an alloy of high magnetic permeability.
Mounted in jeweled bearings, it turns freely, following the maganetic field to move the pointer across the scale.
The samarium cobalt magnet is mounted at one end of the range spring and rotates the helix without mechanical linkages.
