AC dielectric cure monitoring, also referred to as Dielectric Analysis (DEA), measures a polymer’s capacitance and resistance, which are bulk properties utilized in the conventional electrical model ...

Lee was in an R&D group at MIT developing cure monitoring in the 1980s. He founded a spin-off, Micromet Instruments, in 1982 to commercialize this technology. Micromet was acquired several times. In ...

It is important to understand the characteristics of both AC and DC measurements, as both can probe the cure state of thermosets and composites, so it is vital to have a clear outline of the benefits ...

When working on simple DC systems, a small low-cost multimeter from the hardware store will get the job done well enough. Often they have the capability for measuring AC, but this is where cheap ...

Lake Shore Cryotronics’ M81-SSM offers DC, AC and lock-in source and measurement. Synchronous modularity The M81-SSM controller shown with two source modules (left); two measure modules (right); all ...
