WBA-505/WBA-504 Fully Automatic Density Refractometer

Kyoto Electronics KEM Automatic Density Refractometer (WBA-505/WBA-504) General Concentration Meter

Kyoto Electronics KEM Fully Automatic Density Refractometer, Japan（WBA-505/WBA-504）

Fully automatic density refractometer（WBA-505/WBA-504）Instrument Features:

1. Built in density and refractive index measuring cells, requiring only a small amount of liquid sample to measure both density and refractive index simultaneously.

2. Equipped with a built-in Peltier constant temperature device, it can set temperature and automatically control, with fast measurement speed and high accuracy.

4. The density measurement cell has viscosity correction function, and for high viscosity samples, automatic density compensation is applied during density measurement.

5. Wide measurement range, measuring the density (specific gravity/relative density) and refractive index (refractive index) of various liquid samples.

6. Can be connected to an external CHD-502N fully automatic sampler, which can automatically inject, clean, dry, and continuously measure samples.

7. PC cards can be purchased to expand data parameters, storage, and concentration conversion tables. Optional data collection software is available.

8. A comprehensive measuring instrument that combines a density meter and a refractive index meter, capable of measuring both density and refractive index at once.

9. Fully automatic digital display, replacing manual density meters (specific gravity meters), density bottles (specific gravity bottles), and Abbe refractometers.
