Model: OH-6600 – Copper–aluminum dual-polarity plate
The OH-6600 plate teaches the difference between positive and negative pole sensations.
Copper stabilizes and grounds; aluminum diffuses and relaxes.
Standing or placing hands on the plate creates an educational contrast between hot/cold, dense/light, active/passive sensations.
This tool trains sensory discrimination and body awareness.
Under Law 31, it is classified as a pedagogical polarity-learning tool.
