METER ERROR by MIX DESIGN

Wagner Meters conducted an in-house case study, evaluating the accuracy of the C555 Concrete Moisture Meter against the top leading concrete moisture meter manufacturers, across nine varied and commonly used concrete mix designs in the United States. Recognizing that different concrete compositions dry and react differently, our study was designed to encompass a broad spectrum of mixes—ranging from those with fly ash and air entrainment to mixes fortified with fibers or modified with accelerators and retarders.

The graph provided illustrates the average moisture meter error when testing these specific mix designs. Our findings were compelling: the C555's readings were consistently closer to the benchmark oven-dry results compared to others, solidifying its status as twice as accurate as the leading concrete moisture meters.

This study underscores the C555's superior performance, ensuring that professionals working with any mix—from lightweight aggregates to those with various admixtures—can rely on the C555 for the most precise moisture readings, critical for the integrity and longevity of their concrete projects.
