Introduction
A density balance is a balance used to measure the density of the solids and the liquids by the buoyancy method, and it is used in the laboratories, the quality control, the materials, the research, and the many other applications. The density balance consists of a precision balance, a density kit with the pan and the sinker, and the software or the calculation, and it measures the density by the weighing of the sample in the air and in the liquid, with the density calculated from the weight difference by the Archimedes principle; the density balance is used for the measurement of the density of the solids, such as the metals, the plastics, and the ceramics, for the measurement of the density of the liquids, for the measurement of the specific gravity, for the quality control, for the materials testing, and for many other applications, and it provides the density value, with the automatic calculation; the density balance is an essential instrument for the density measurement. Density balances are used in the laboratories, in the quality control, in the materials, in the research, and for many other applications. With their buoyancy method, density balances are essential for the accurate density measurement.

FAQ
Q1: What testing scenarios is this balance mainly applied to?
A: The density balance is used in jewelry and gemology, metallurgy, plastics and rubber manufacturing, material testing, quality control and research laboratories to measure the density or specific gravity of solid and liquid samples using the Archimedes principle. It supports precious metal purity verification for gold, silver and platinum jewelry, gemstone identification and authenticity testing, metal alloy composition assessment, plastic and rubber material quality control, ceramic and glass density measurement, and material characterization for research. The density measurement provides a rapid, non-destructive indicator of material composition, purity and quality. It is essential for jewelry manufacturers, gemological laboratories, metal processing facilities, plastics and rubber producers, and material testing laboratories requiring accurate density measurement for purity verification, material identification, quality control, product specification compliance and research, where density correlates with material composition, porosity, purity and physical properties across multiple industries.
Q2: What standards does the balance comply with?
A: The density balance supports methods referenced in ISO 1183 for plastics density, ASTM D792 for plastics, ASTM D297 for rubber, ISO 2781 for rubber, and relevant GB/T standards. The balance complies with OIML R76 and relevant GB/T standards for non-automatic weighing instruments. Calibration should use certified weights and density reference standards traceable to international standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole balance is covered by a 12-month warranty. The weighing cell, electronics and density kit are covered, while beakers, thermometers and calibration weights are accessories or consumables. Damage from improper use, overloading or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in density measurement technique and balance operation. We provide an operation manual and remote guidance. Proper sample preparation, immersion technique, bubble removal and temperature measurement are important for accurate density results.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Balance calibration with certified weights recommended every 6-12 months, or more frequently for high-precision use. Density verification with a reference standard of known density periodically. Routine level check and cleaning before each use. Temperature measurement calibration if integrated.
Q7: Are supporting consumables universal?
A: Calibration weights, beakers and density reference standards are available from laboratory suppliers, though certified weights are recommended for accuracy. Long-term consumable cost is very low for a density balance.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes balance capacity and readability, density kit type (solid or liquid), sample holder and data output. Additional weights, beakers and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: No complex installation is required beyond leveling and power connection. The package includes the balance, density kit and instruction manual. On-site calibration and training service are available at additional cost for quality control laboratory setup.
Q10: What types of samples are compatible with this equipment?
A: The density balance measures density of solid samples (within the balance capacity and kit size) and liquid samples using appropriate accessories. Porous samples may require wax coating or vacuum impregnation to prevent fluid absorption. Very small or very light samples require higher precision balance. Samples must be fully immersible without dissolving in the reference fluid. Users should select appropriate reference fluid (water or other), ensure no air bubbles adhere to the sample, measure fluid temperature accurately, calibrate the balance regularly, and handle samples carefully to avoid errors from surface tension or incomplete immersion.
