  • The industry standard in indicating low air or gas pressures of positive, negative, or differential pressures
  • Large, easy-to-read 4" (102 mm) dial
  • No manometer fluid to evaporate, freeze, or cause toxic or leveling problems
The Magnahelic guage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems, and pressures in fluid amplifier or fluidic systems. 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.

  • Q:

    Measuring PSID across an industrial boilers' feedwater economizer. Temp range 250 deg F to 280 deg F . Pressure ranges from 570 psig (from the pumps) feeding into a boiler steam drum at 470 PSIG. While I don't have any way of knowing what the normal differential is, I'd guess it to be 5 psid to start. Which one of your units do I want? I need 6

      A higher temperature range option would be 68462-43 which has a 0-5 psi range and 20-200F operating temperature.

  • Q:

    Can I use a differential gauge rated for a max of 15psi to measure a filter's condition in a line of 80psi. Gauge is 0-10 inches of water.
    Asked on 10/16/2014 by Randy

    1 answer



      No, this gauge would not be able to tolerate the line pressure of 80psi. We offer a high pressure alternative of this differential gauge which is part number 00350TG.
