Brief introduction JL-1206 type true density measurement instrument, Archimedes (density = mass / volume) principle, change traditional pycnometer test medium to small molecule inert gas, using Boyle - Mariotte's law, of the samples were calculated not by volume, the relative density, and the pores of the porous material rate analysis and test of rigid cellular plastics open cell and closed cell volume percentage. Automatic control of the microprocessor, the testing principle of gas expansion method based on Rapid Determination of true density of powders and bulk solids, high precision, good repeatability. Features 1 sample pool size adjustable to accommodate different sample size, the test conditions of optimization, to achieve better test results. 2 the number of tests can be set, a single test can quickly get results, analysis of the shortest running time of about 1 minutes. Can automatic continuous test. 3 can use compressed air as the test gas. 4 adjustable pressure, to eliminate the pressure so that the measurement error caused by the deformation of the sample, the sample nondestructive. 5 there are 2 sample pools, where the micro sample cell is tested for micro size samples. 6 test of open cell and closed cell foams can be volume percentage, porosity of porous materials analysis. Technical parameter 1 measuring volume range: 0.01 ~ 100cm3 2: the accuracy is better than ±1% 3 repeatability: better than ±1.5% 4 Analysis of gases: compressed air or helium, nitrogen 5 analysis time: < 3 minutes
