Presidium PMuT III Multi Tester

Tell a diamond from moissanite, a diamond simulant, or cubic zirconia at the bench in a single test. The Presidium PMuT III Multi Tester is a premium all-in-one instrument that combines thermal and electrical conductivity testing to identify diamonds, moissanite, diamond simulants, and cubic zirconia. Designed for professional jewelers who need fast, reliable stone identification, this tester delivers nearly instantaneous results through an intuitive color-coded LED indicator system and audible alerts, eliminating guesswork at the bench.

Simply place the retractable probe against the stone to be tested. The visual indicator illuminates in one of four colors: orange for metal, red for simulant, yellow for moissanite, and green for diamond. An intermittent beep sounds when metal is detected, while a confirmed diamond result produces a continuous beep for added certainty.

The PMuT III runs on three AAA batteries (not included) or an optional 110V AC adaptor.

Features

• Combines thermal and electrical conductivity testing in one instrument
• Identifies diamonds, moissanite, diamond simulants, and cubic zirconia
• Retractable probe for safe, precise stone contact
• Color-coded LED results: orange (metal), red (simulant), yellow (moissanite), green (diamond)
• Audible alerts: intermittent beep for metal, continuous beep for diamond
• Near-instantaneous test results
• Powered by three AAA batteries or optional 110V AC adaptor

Notes

The 110V AC adaptor is highly recommended for regular bench use. As a high-drain device, the PMuT III can deplete three AAA batteries in less than 2½ hours of continuous operation. Batteries are not included.
