Fully automatic density refractometer DA-645+RA-600

Desktop digital density refractometer WBA-504

The main features of the desktop digital density refractometer WBA-504 are:

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.
3. The density measurement cell has a viscosity correction function, which automatically corrects the viscosity of high viscosity samples during density measurement.
4. Wide measurement range, measuring the density (specific gravity/relative density) and refractive index (refractive index) of various liquid samples.
5. It can be connected to an external fully automatic sampler (CHD-502N), which can automatically inject, clean, dry, and continuously measure samples.
6. PC cards can be purchased to expand data parameters, storage, and concentration conversion tables. Optional data collection software is available.
7. A combined measuring instrument of density meter and refractive index meter, which can simultaneously measure both density and refractive index indicators.
8. Fully automatic digital display, replacing manual density meters (specific gravity meters), density bottles (specific gravity bottles), and Abbe refractometers.
9. It is suitable for essence, tobacco, daily chemical, beverage, food, aviation fuel, petrochemical and other industries.
