Direct reading density balance

Density of the electronic balance can be performed in four density measurement method, these methods are as follows: 1. Two solid density greater than water. 3 solid density less than water. Liquid density 4. Porous materials (infiltration oil bearing materials) excellent performance:. 1.60M ARM processor 2 the latest high-speed digital processing technology, fast and stable weighing results obtained 3 friendly interface: 4 wide viewing angle Intelligent LCD backlighting . direct reading display 5 Density - Density is measured by means of Archimedes (buoyancy method) to be achieved, this method can be of solid, liquid and density of the porous material. Density measurement principle i) the ratio of the density of an object is its mass and volume, the specific formula: ρ = m / V ii) the density measurement is performed by the Archimedes' principle. The Rationale: immersed in the liquid of each solid lose weight equal to the weight of its liquid. iii) a solid density is usually measured using a liquid of known density (e.g.: water or ethanol) as the auxiliary liquid, the solid mass measured in air by (A) and the auxiliary liquid (B) successively weighed can be calculated After its density measurements obtained using methods generally solid density, the steps are as follows (refer to the liquid is water or alcohol) 1) Press "Function" key until the screen displays the first line of "DENSITY", release the key 2) Press "OK" button to select the sample density determination form the second line of the display flashing prompt "SOLID solid" or "LIQUID liquid" 3) Press the key to select the solid front and rear measure "SOLID" 4) Press the "OK" button to confirm Sample Form 5) Press button to select the auxiliary liquid water before and after (WATER), alcohol (ALCOHOL) or other (OTHER). 6) Press the "OK" button to display the selected auxiliary liquid at this time prompted the current temperature of the liquid. 7) followed by a short press key to enter the current temperature before you can press the "OK" button to confirm and move to the next digit Set the input bits finished, press the "OK" button to confirm the save 8) Set whether the material is porous solid material PROROUS) is a porous material Press "OK" button, or press the button, select "SET OFF" 9) Press "OK "to wait for the weighing scales in the air sample weight 10) on the measurement of solid Cradle to get the air sample weight 11) Press" Function "key and then the measured solids into liquids weighing its auxiliary auxiliary liquid weight 12) Short press "function" button that was the object of density units is G / CC that g/cm3.
