Series 250/451 | Inclined Manometer Air Filter Gages Precision Machined, Solid Acrylic Plastic Gages, Accurate to ±1% of Full Scale |
|
FEATURES Highly accurate and easy to use yet almost indestructible, Dwyer® Series 250-AF Inclined Air Filter Gages are foolproof and dependable. There are no moving parts - no mechanical linkages - nothing to wear out, jam or deteriorate from vibration. They never need calibration. The mirror polished inclined scale allows the operator to easily read minute differences in differential pressure across the filter accurately without parallax error. The only servicing required is occasional zeroing. If cleaning is necessary, it is easily done with soap and water.
