FAQ

What is the JH series Gold densimeter and how does it work?

The JH series Gold densimeter is an instrument designed to measure the density of gold and gold-containing samples. It operates on the hydrostatic (Archimedes) principle by comparing the sample's weight in air and its apparent weight while immersed in a liquid (usually distilled water). From those two readings the device calculates density, which is used to infer gold purity or identify different alloys.

What kinds of items and application scenarios is the JH densimeter suitable for?

Typical applications include jewelry testing (rings, chains, bracelets), bullion and coin verification, refinery and assaying support, pawnshop and retail checks, scrap and recycling grading, and field checks in mining or samplers. It is well suited for solid, non-porous metal objects and items whose density is representative of their metal content.

How should I prepare a sample and perform a measurement for reliable results?

Clean the sample of dirt, oils or loose particles; remove detachable non-metal parts if possible. Dry the item for the air weight step, then suspend it from the instrument’s hook and record the weight in air. Next, immerse the sample in the recommended liquid (distilled water) without touching the vessel sides or bottom and record the immersed weight. Ensure no air bubbles cling to the surface and that the sample is fully submerged. Use the instrument’s function to compute density and, if applicable, estimated fineness/purity.

How accurate is the JH series and what do I need to calibrate or correct for?

Accuracy depends on model resolution and operation quality. For best results, calibrate the balance with certified weights regularly, and use temperature-corrected water density values because water density changes with temperature. Use distilled water and ensure stable ambient conditions (no drafts, vibrations). Follow the manufacturer’s recommended calibration and verification procedures to maintain stated accuracy.

What are common limitations and cases when the densimeter may give misleading results?

The instrument measures bulk density, so it cannot reliably determine layered or plated structures (thin plating over a different core), hollow objects with trapped air, porous or highly irregular items, or small particulate samples without a proper holder. Surface coatings, adhesive residues, or bubbles can skew results. In such cases complementary tests (XRF, fire assay) may be required for definitive composition.

What routine maintenance and troubleshooting steps should I follow if readings are unstable or incorrect?

Keep the balance and immersion vessel clean and free of residues; replace the immersion liquid periodically and remove trapped bubbles. Check that the sample is securely hung and not touching the vessel walls. Verify instrument level and stability; avoid drafts and vibrations. Recalibrate with certified weights if readings drift. If readings remain unstable, consult the manual or contact technical support — possible causes include a damaged load cell, electrical noise, or a damaged suspension hook.
