Air Filter Gauge 25

This compact inclined-vertical air filter gauge measures, with accuracy to ±3% of full scale, pressures both above and below atmospheric, as well as pressure differentials. A logarithmic curve-shaped tube provides high range capacity with large, more easily read increments at low readings. The operating range is 0 to 3 inches water, with divisions of .01 inches water at the low end scale, and .120" inches water at the high end. This gauge is simply constructed of molded acrylic plastic and is suitable for use in ambient temperatures from -20° to +159°F.

Unit includes: 8 feet of flexible double column plastic tubing, two tubing connectors for 1/8" pipes, two mounting screws, 3/4 oz. bottle of indicating fluid, red and green pointer flags, and instruction manual.
