Distilled water keeps densimeter baselines consistent. Tap minerals add drift and tank film.
Use room-temperature distilled water, label a jug for densimeter only, and change it when cloudy.

FAQ
Can a densimeter test hollow or gem-set jewelry?
No. Trapped air and stones break the volume math. Solid metal only—or remove stones / decline the piece.
Is a densimeter the same as a fire assay or XRF?
No. It is a first-pass density/karat screen. High-ticket or disputed lots still need XRF or assay.
Do I pay more using your Amazon links?
No. You pay the same Amazon price. We may earn a commission if you buy through our links.
