Digital fully automatic density meter DA-640

Kyoto Electronics KEM Digital Fully Automatic Density Meter DA-640, with a Chinese operating interface, the instrument meets the precision and repeatability requirements of GB/T 29617 and ASTM D4052, with small sample size and fast speed, single point temperature calibration, and automatic viscosity correction. Definition: Density: The mass of a substance divided by its volume, expressed in kg/m3 or g/mL. Relative density: The ratio of the density of a substance at a certain temperature to the density of water at a specific temperature. API gravity: A standardized scale used by the American Petroleum Institute to indicate the specific gravity of oil products. A specific function of relative density (specific gravity) at the corresponding temperature.

Main features:

1. The density meter has high measurement accuracy, fast measurement speed, and small sample size.

2. Automatic viscosity correction function, no need to input the viscosity value of the sample.

3. Built in sample pump, automatic sampling, cleaning, and drying measuring cell.

4. High brightness LED background light source, convenient for direct observation of the measurement cell.

5. Smooth joint, no bubbles or pollution, easy to clean.

6. Input the density and concentration comparison table and convert the concentration of the sample.

7. Optional injection/cleaning device or multi sample automatic injection device.

8. The densitometer can be connected to an external refractometer to simultaneously measure density and refractive index.

9. Compliant with GLP regulations, store results, inspection and calibration records.
