Abstract

The invention relates to the field of density measurement devices, and discloses an electronic balance density measurement kit device. The electronic balance density measurement kit device comprises asupport frame, a sample holding mechanism and / or buoyancy mechanism and a beaker bracket, wherein the support frame has an axisymmetric structure with a symmetrical central line, and the bottom end can be connected to a scale seat of an electronic balance; the support frame is connected to the scale seat of the electronic balance in such a manner that the center of gravity of the support frame and the weighing center of the electronic balance are positioned on the symmetrical central line of the support frame; the sample holding mechanism and / or buoyancy mechanism can be arranged on the support frame, and extends towards the bottom end of the support frame along the symmetrical central line of the support frame; the beaker bracket can be supported on a panel of the electronic balance; a gap is formed between the beaker bracket and the support frame. By adopting the electronic balance density measurement kit device, the center of gravity of a measured object can be controlled within asmaller radius region which takes the weighing center of the electronic balance as a dot, so that the measurement result of the electronic balance is more accurate.

Description

technical field [0001] The invention relates to the technical field of density measuring devices, in particular to an electronic balance density measuring kit device. Background technique [0002] In the application of electronic balance, there is a detection function for the density of the measured object, which is determined by Archimedes principle. When measuring the density of a solid, the weight of the measured object is measured in air and water, and the density of the measured object is calculated using the buoyancy formula; when measuring the density of a liquid, an object with a known volume is used to intrude into the water and measured using a balance The buoyancy force on the intruding object, according to the formula buoyancy F=ρ 液 gv 排 , the liquid density can be measured. At present, devices with similar functions on the market are mainly single-arm supports, and the structural materials are all metal, which will bring two problems: [0003] 1. The overall...
