Use Series 1227 as a regular U-tube manometer to read high-range pressure on the right leg, or as an inclined manometer to read low-range pressure on the bottom leg. Simply incline manometer until fluid levels read zero. No spirit level required. Magnetic clips hold the gage in position on a steel duct surface.

Most versatile and useful low cost manometer we know of. Designed for installation and servicemen. A sturdy, clear plastic manometer, it offers single, direct readings in two ranges: As a U-tube, it reads from 0 to 16" of water; as an inclined gage, it reads from -.20 to 0 to 2.6" of water. Model 1227M (Metric) is 0 - 400 mm water column as a U-tube and -5 to 0 to 70 mm water column as an inclined gage. "How-to-use" instructions are printed directly on the scale.

Indicating Tubing -
Clear .400" O.D. tough, shatterproof butyrate. Pressure connection end is bent to provide over pressure protection when used as an inclined gage. One 4-1/2' x 3/8" Tygon tube included for pressure source connection.

Scale -
Stark white high-impact styrene, 21" long. Adjustable for precise zeroing.

Markings -
1" major, .2" minor graduations on high range; .02" graduations on low range (50 mm major, 10 mm minor graduations on high range, 10 mm major, 1 mm minor graduations on low range for metric model). Silkscreened in black on stark white for positive definition. Acrylic-coated for permanence.
