Page 4: Introduction
Purchase at www.scaleman.com 1. Introduction Thank you for purchasing the AD 1654 density determination kit. The AD 1654, when combined with one of A&D electronic balances (HR-AZ / HR-A and FZ- / FX- series), allows the density of a solid and liquid to be measured easily. -

(0.99997 g/cm 3-3. Archimedes’ Principle Of Density Measurement The AD-1654 is combined with an electronic balance to measure the density of a sample based on the Arichimedes’ principle. Arichimedes’ principle A body immersed in a liquid (or a gas) is subject to an upward force equal to the weight of the liquid (or the gas) it displaces. -

Purchase at www.scaleman.com 4. Error Factors The results of measurements may be affected by various factors that could cause errors 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: d : Density of air (g/cm 0.0012932... -

Purchase at www.scaleman.com 4-4. Influence Of Wire In solid density measurement, the surface of the liquid rises when a solid sample is placed on the density pan, which is immersed in the liquid, At this time, the buoyancy corresponding to the weight of the raised liquid is exerted on the wire (diameter of 1 mm) connecting the upper and lower pans. -
