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.

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.
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...
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)
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.
MEASURING THE DENSITY OF A SOLID Assemble the kit as described in the procedure below. Note that the assembly procedure depends on the balance model. 5.1. Assembling the Kit: BM / GH / HR-i Series Note: The kit can not be used with the BM-20 and BM-22 of the BM series balances. Assembled view Density pan Thermometer...

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).

6.2. Measuring the Density of a Liquid Use the following procedure to obtain the density of a liquid. With the float hanging, press the RE-ZERO key to set the displayed value to zero. Example display: BM Pour the liquid of which you want to measure the density into the beaker.
FREQUENTLY ASKED QUESTIONS Questions Answers Use a liquid that has a lower density than water and I’d like to measure the density of a resin does not dissolve the sample, such as methanol pellet or sheet, which floats in water. Is it (density 0.798) or kerosene (density 0.80).
