Density measurement range:0.00000~3.00000 g/cm3
1.Specification
Density is one of the important physical properties of liquids. According to the density, it can help understand the purity and doping of substances. The automatic density meter is widely used in the petroleum industry, oil industry, pharmaceutical industry, food industry, and daily chemical industry. , Sugar industry, flavors and fragrances, cosmetics industry and other related factories, schools, research institutes and testing institutions indispensable one of the common equipment. The D605 automatic density meter adopts the U-shaped vibrating tube detection principle, which can directly detect the density (relative density) of the liquid, which reduces the workload of personnel sampling, temperature control, calculation and cleaning, and realizes rapid density detection. It has the characteristics of low sample consumption, automatic measurement, fast test speed and good repeatability.
2, Introduce
Adopting the working principle of U-shaped tube vibration, it can quickly measure the density of liquid, with electronic excitation, vibration frequency counting and display functions. By injecting a small amount of sample into the vibrating sample tube, according to the change in the vibration frequency of the sample tube, combined with the calibration data, the density of the sample is calculated.
A. Operation interface: color LCD touch screen display, the operation is more intuitive and convenient.
B. Small injection volume: only 2~3ml samples to be tested are needed each time, saving resources and reducing costs.
C. Measurement mode: Built-in multiple measurement modes such as alcohol concentration, sugar concentration, acid and alkali concentration.
D. Temperature control: Peltier temperature control device (Peltier), precise temperature control.
E. Instrument calibration: the error calibration is simple, just use air and distilled water to calibrate the instrument.
F. Communication interface: equipped with a variety of communication interfaces, data can be saved, exported and printed.
