424 Durablock Inclined/Vertical Manometer
Inclined range bore has a length of 20 in, accuracy to ± 0.25%, and parallax-free reading
Dwyer® Series 420 inclined-vertical manometer are extremely accurate instruments designed and made especially for precision measurement of low differential pressures in laboratory and test applications. The inclined range bore has a length of 20 in to provide ample multiplication of indicating fluid movement in this critical lower part of the range
• 1-1/4 in thick acrylic plastic body is a solid block, virtually unbreakable, stable and absolutely free of the danger of distortion.
• 3/16 in bores, accurate to ± 0.0002" are permanently free of bends or crooks, will not require recalibration because of distortion.
• Ground glass bubble level sensitive to 115-125 sec./2 MM. is 1-1/2" long x .375" diameter and provided with two red lines for easy visibility and alignment.
• Parallax-free reading for maximum accuracy and consistency is achieved by simply aligning the meniscus with its image reflected in the polished aluminum scale.
• Selected gage fluid with high wetability characteristics forms a consistent, well shaped meniscus for perfect readability.
• O-Ring sealed fluid level plunger adjustment for easy zeroing.
• Precision built to assure device meets the highest standards.
• Low pressure laboratory and test applications
