Plastic films, powders, and pellets are typically very low in moisture content. Consequently, many secondary moisture analysis techniques do not supply the necessary accuracy and repeatability. For laboratory analysis, the Model MCPC: Lab Moisture Analyzer, which utilizes capacitance, dielectric RF measurement, is useful for plastics moisture analysis. In addition to measuring the dielectric properties of the plastics, a beam load cell is incorporated to make readout adjustments due to any variations in sample cup fill level. A bulk density measurement is also supplied along with an accurate instantaneous moisture analysis.
