京都電子工業株式会社KYOTO ELECTRONICSMANUFACTURING CO.,LTD.APDA-0237en-1 APDA-0237en-16.Example Application Note Density/relative density (Specific gravity) / APl gravitymeasurements of lubricating oil Industry Petroleum Instrument Density/Specific gravity meter +Auto Sampler Measurement method Resonant frequency oscillation Standards ASTMD4052 1. Scope ASTM D4052 prescribes a method for measuring the density, relative density and API gravity ofpetroleum products (liquid samples) by a digital density meter. The KEM density/specific gravitymeter used in this measurement conforms to this standard and can be used to make measurementsautomatically in combination with an Auto Sampler. This application shows an example of the measurement of density (specific gravity) / API oflubricating oil using an Auto Sampler (Note 1). 2. Precautions The correct values will not be obtained if there are bubbles in the sample. Remove any bubblesby heating the sample or using ultrasonic cleaning equipment before placing the sample in AutcSampler. 3. Apparatus Equipment Density/Specific gravity meterOption Auto Sampler 4. Reagents Rinse liquid 1 Toluene Rinse liquid 2 Acetone Using toluene as Rinse liquid 1 increases the rinsing efficiency by dissolving any lubricating oiladhering to the cell. 5.Procedure -C(alibration - · Place a sample vial containing pure water in Auto Sampler and perform the calibration. -Measurement- Place a sample vial containing the sample in Auto Sampler, and perform the measurement. To perform calibration followed by sample measurement automatically, set both the purewater for calibration and the sample. The Auto Sampler can also automatically sampling, measurement (calibration), rinse and drythe cell. 京都电子工业株式会社-可睦电子(上海)商贸有限公司 上海市徐汇区宜山路333号1201室 电话:021-54488867 电邮: kemu-kem@163. com -Parameter- .The measurement parameters are set by the customer (see the table below).
