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 to 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.

Good for measurement but Very expensive for the type of construction. Will break easily.

Same as I learned on in school 21 years ago. They’ve worked for years. Only accurate monometer you actually can use. I wish it had silicone hoses is all.

using it to check static pressures in my furnace and ductwork. Works great and helped my find where my air restriction was.
