Dielectric Analyzers

The LT-451 Dielectric Cure Monitor is a compact, versatile instrument designed for Research & Development, Quality Assurance/Quality Control, and Production applications involving thermoset materials–resins, composites, paints and coatings.

The wide 0.001 Hz – 100 KHz frequency range of the LT-451 allows frequency sweeping for studies of dielectric properties, and sensitivity to very high resistivity and ion viscosity (very low conductivity and loss factor). The associated thermocouple input allows correlation of temperature with cure rate and material properties.

The LT451 is available with one, two or four channels. Each channel consists of one dielectric sensor input and one thermocouple input. Instruments may be upgraded at any time with additional channels, and an external four-channel multiplexer is available. Dielectric inputs may be ordered for either mid-conductivity or high-conductivity ranges.

The CureView Data Acquisition Software has functions for defining cure monitoring parameters; data acquisition, analysis and recall; plotting and printing.

When used with either disposable or reuseable dielectric sensors, also available from Lambient Technologies, or the user’s own sensors, the LT-451 Dielectric Cure Monitor and CureView data acquisition software form a complete measurement system for studying dielectric material properties in all processing environments.
