数字式液体密度计 测量甲苯的密度

DAZ-07094Kyoto Electronics Manufacturing Co.，Ltd.Data No. RL09-07076 KEM Application Note Density Measurement Density measurement of Toluene -Summary- Checked the reproducibility of measuring density of Toluene by DA-510. Consequently， good reproducibility was obtained， and SD was 0.00001g/cm(n=10). -Measuring instrument- Main unit： DA-510 Density meter -Rinse solution- Rinse-1： Rinse-2： Acetone -Measurement method- (1) Set the measurement temperature at 20°C. (2) Factor calibration is performed by dry air and degassed pure water. (3) Aspirate the sample into the measuring cell with the built-in pump and measure thedensity. -Equation- -Ambient condition- Ambient： 23.5°C Humidity： 59% Weather： Fine -Reference- 京都电子工业株式会社-可睦电子(上海)商贸有限公司 -Measurement parameter- -Printout data- Measurement Parameter Method No. ： 0 Method Name ： TOLUENE Temperature ： 20.00°C Stability ： 0 Limit Time ： OsSequence Off Calib. ： Air&Water ***Result：* *Sample No. 03-01 Meas.
