Analysis Principle : Gas replacement method is based on volume of the gas a substituted a liquid measurement sample the discharged . This method excludes the possibility of liquid immersion method pair sample is dissolved 's , having a the advantage of not damaging the sample of . , Application gas displacement of Archimedes principle ( density = mass / volume ) , using small molecule diameter inert gas under certain conditions of Bohr 's law (PV = nRT), accurate measurement of true volume the material being tested , to thereby obtain its true specific gravity . Technical parameters: Analysis Methods: gas replacement method Determination of Volume range : 0.01 ~ 100 cm3 Analysis Number of warehouse : 2 Precision degree : better than ± 0.06% Repeatability : better than ± 0.04% Gas path control system: six one of the the solenoid valve control module Software control system : INTERNET Remote Control Gas analysis : pure helium or nitrogen Sample analysis time: less than 8 minutes Instrument control : 10 -inch high resolution LCD touch screen Instrument volume : 680 * 360 * 290mm Features: 1. The test of high precision, good accuracy, solve the problem of immersion method of sample dissolution. 2. The whole testing process does not change the measured the physical properties of the sample. 3. The test speed: 2-8 minutes to complete the whole test process. 4. Applicable range: can be used to measure all kinds of powder, granule, block of solid samples and non-volatile liquid samples. 5. Wide range of test: the density of the sample size is not restricted. 6. The real full automatic operation: microprocessor control fully automatic operation, avoid the error caused by artificial operation. 7. There are three different sizes (10, 50 and 135 cc) sample pool, can replace each other, to adapt to the measurement of different sample size range. Each sample pool of calibration data is stored in the permanent memory.
