Abstract
Methods and apparatus are disclosed for calibration determinations for handheld moisture meters in the field. A calibration reference stand emulates a sample with an equivalent moisture content, allowing rapid determination whether a moisture meter is out of calibration, or determination of a new calibration value. The calibration reference stand includes an electromagnetic load, which can be formed of a metal sheet or high dielectric constant material, supported on a platform, and mechanical fixturing for reproducible positioning of a moisture meter on the stand. Associated methods and variations are disclosed.
