Differential Pressure gauge Magnehelic Gauge

Differential Pressure gauge Magnehelic Gauge

Product Details

Type Magnehelic
Material Metal
Color Black & White
Shape Round

Mounting - A single case size is used for most models of Magnehelic® gages. They can be flush or surface mounted with standard hardware supplied. Although calibrated for vertical position, many ranges above may be used at any angle by simply rezeroing. However, for maximum accuracy, they must be calibrated in the same position in which they are used. These characteristics make Magnehelic® gages ideal for both stationary and portable applications. A 4-9/16 hole is required for flush panel mounting. Complete mounting and connection fittings, plus instructions,are furnished with each instrument
