422-250MM

422-250MM is a Dwyer® series 420 Durablock® inclined-vertical manometer. This is 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" to provide ample multiplication of indicating fluid movement in this critical lower part of the range. Typical application include low pressure laboratory and test applications.

• 0-25mm w.c. Inclined & 30-250mm w.c vertical
• Long bore length provides ample room for fluid movement for low range sensing
• Precision built to assure device meets the highest standards
• 1-1/4" thick acrylic plastic body, virtually unbreakable, stable and free of danger/ distortion
• 3/16" Bores, accurate to ±.0002" are permanently free of bends or crooks
• O-RING sealed fluid level plunger adjustment for ear zeroing
• Precision built to assure device meets the highest standards
