Free and Bound Moisture in Gypsum

Quickly determine gypsum purity

If you work with gypsum, you know how crucial moisture measurement is to making a high-quality product. Computrac® understands; that’s why Computrac has been the de facto industry standard for moisture measurement in gypsum for decades. The Computrac MAX® 4000XL will provide accurate results quickly for free moisture, bound moisture, and gypsum purity. If you need even more information about your gypsum, the Computrac MAX® 5000XL can even determine the residual paper content of recycled wallboard. Whatever your needs, the Computrac® family of moisture analyzers will enable you to quickly obtain reliable, repeatable moisture content results, independent of operator skill.
