DH-300L digital liquid density hydrometer DH-300L digital liquid density tester, using Archimedes' principle and modern electronic technologies, direct digital display density, high accuracy, stability and durability. Compared with the traditional method Wechsler scales, pycnometer method, the machine operation more simple, and not affected by external factors and temperature, enabling fast and accurate measurements. The liquid density meter for measurement: solvents, adhesives, paint, asphalt, inks, resins, chemical oil, edible oil, food additives, beverages, dairy products ... and other fields. Technical parameters: 1. Density resolve: 0.001 g / cm3 2. Measuring range: 0.001-99.999g / cm3 3. Measuring range: 0.005-300g 4. Measurement category: mobile liquid, viscous liquid, volatile liquid, corrosive liquid, high-temperature liquid, suspension liquid, emulsion liquid ... and other measuring principle: Archimedes displacement method output: RS-232C standard communication interface to facilitate the test data and print output power: AC ~ 220V / 50HZ measurement procedures: ① will be filled with the sample measuring cup placed on measuring board placement, after deducting the weight of the hook. ② Hook the standard weights hanging and fully immersed in the liquid to be measured, the display density values. Standard accessories: ① host, ② measure placing plate, ③DE-20A standard liquid measurement components, ④ forceps, ⑤ thermometer, ⑥100G weight, ⑦ wind dust cover, ⑧ measuring stand, ⑨ power transformer a ※ DE-20A standard liquid measurement Components: Includes two stainless steel hooks, weights a standard glass, stainless steel weights a standard measuring cup 2
