Cole-Parmer Magnehelic Differential Pressure Gauge is the industry standard for indicating low air or gas pressures, including positive, negative, or differential pressures. Designed for accuracy, durability, and ease of use, it ensures reliable readings in industrial and laboratory environments.
Product Features
- 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
- Measures 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
- Motion damped with high-viscosity silicone fluid for smooth readings
- Zero adjustment screw conveniently located in the plastic cover, accessible without removing the cover
- O-ring seal provides pressure tightness
- Rugged design resists shock, vibration, and overpressure
- Helix precision-made from an alloy of high magnetic permeability, mounted in jeweled bearings
- Helix turns freely following the magnetic field to move the pointer across the scale
- Samarium cobalt magnet mounted at one end of the range spring rotates the helix without mechanical linkages
What’s Included
- Two 1/8" NPT plugs
- Two 1/8" rubber tubing adapters
- Three mounting adapters with screws
