The Model MCPC Laboratory Moisture Computer uses the principle of weight-corrected capacitance measured at radio frequencies to determine a physical property (dielectric constant) that can be related to moisture content. This technique is useful in measuring moisture because RF completely penetrates nonconductive materials and therefore can gauge moisture throughout the material. The test is instantaneous and completely nondestructive, and no sample heating or chemicals are required. The Model MCPC is often used as a safe and inexpensive replacement for the Karl Fischer chemical titration moisture analysis. It also replaces heat lamp 'moisture balance' type heating devices.
