Description

The YR06704//YR06704-4 series density balance is a high-precision instrument designed for the reliable determination of density in solids, liquids, powders, and absorbent materials. This instrument combines analytical weighing functions with automatic density calculation, making it a versatile solution for quality control laboratories, research, and the chemical, pharmaceutical, food, and materials industries. Depending on the model, it offers capacities from 210 g to 610 g , with readability ranging from 0.01 g to 0.001 g , ensuring accurate measurements even with small samples (minimum weighing from 0.004 g). Its system allows conversions between units of weight (g, ct, oz) and density (D, %, K), facilitating comparative analyses and standardized technical reports.

Design and technology (functionality)

The balance integrates a 160 x 70 mm weighing pan and a 139 x 100 x 78 mm immersion tank , optimized for hydrostatic testing. Its robust and stable structure minimizes vibrations and errors due to environmental interference within the 5–25 °C operating range. It includes a 200 g calibration weight , ensuring traceability and metrological accuracy. Repeatability (up to ±0.002 g in model YR06704-4) and linearity (up to ±0.003 g) position it as one of the best options on the market for quality control and materials analysis. In terms of price, density balances with these characteristics typically range from USD 1,800 to USD 4,500 on the international market , depending on the model, precision, and included accessories, making this series a competitive alternative in terms of cost-benefit ratio.

Product use in the field

In real-world applications, the YR06704 Density Balance is used to evaluate materials such as plastics, rubbers, ceramics, light metals, resins, oils, solvents, and industrial powders. In quality control, it allows for verification of batch uniformity; in R&D, it supports the development of new materials; and in production, it helps detect early deviations in formulations. The typical procedure involves weighing the sample in air and then submerged in the reference liquid (usually distilled water), automatically obtaining the density without manual calculations.
