    INTRODUCTION Thank you for purchasing the AD-1653 Density Determination Kit. This manual describes how to use the AD-1653 Density Determination Kit. The AD-1653, when combined with one of our electronic balances (BM series, GH series, HR-i series, GR series, HR series and HA series), allows the density of a solid and liquid to be measured easily. Before using the AD-1653, please read this manual thoroughly and keep it at hand for future reference.

  • Page 6: Density Measurement Principles

    DENSITY MEASUREMENT PRINCIPLES 3.1. Density Density refers to the total mass of a sample per unit volume. ρ (Unit: g/cm , etc.) ρ : Density M : Mass V : Volume 3.2. Specific Gravity Specific gravity refers to the ratio of the density of a sample to the density of pure water at 4°C under a pressure of 1013.25 hPa.
  • Page 7: Density Of A Solid

    3.4. Density of a Solid The density of a solid can be obtained according to the weight of the sample in air, the weight of the sample in liquid and the density of the liquid. ρ ρ - d) + d A - B ρ...
  • Page 8: Error Factors

    ERROR FACTORS There are several things that can affect the accuracy of a density measurement. 4.1. Buoyancy of Air A density measurement is influenced by an upward force of 0.0010 to 0.0014 g/cm (buoyancy of air). The density of air can be obtained by the equation below: 0.0012932 P (hPa) 1 + 0.0036728 x t (°C)
  • Page 9: Temperature Of Liquid

    4.3. Temperature of Liquid The density of the liquid that is used for measuring the density of a solid varies with the liquid temperature. Therefore, the decimal places beyond the first decimal place of the measured value contain errors. Obtain the density of a liquid according to the temperature from Table 1 for distilled water or from other reference documents for other liquids.

    5.5. Measuring the Density of a Solid The density of a solid is obtained by averaging the measured values. Start the measurement when water temperature becomes stable. Example display: BM Press the RE-ZERO key to set the displayed value to zero. Place the sample on the upper pan and record its weight in air (A).
