Product details
Combination system of refractometer and densitometer RA+DA
The main features of the refractive index meter and density meter combination system RA+DA are:
1. The digital refractometer and digital density meter are connected for use, and the refractometer can save space above the density meter.
2. Combining a refractometer and a densitometer, this system only requires a small amount of liquid sample and can simultaneously measure refractive index and density.
3. The refractive index and density measurement cell is equipped with a Peltier constant temperature device, which can set the temperature by itself, with fast speed and high accuracy.
4. The densitometer measuring cell has viscosity correction function, and for high viscosity samples, automatic density value correction is performed during density measurement.
5. Equipped with an automatic sampling pump, it is convenient for sampling, draining, cleaning, and drying. Equipped with automatic dryness judgment function.
6. Wide testing range, capable of measuring the refractive index (refractive index) and density (specific gravity/relative density) of various liquid samples.
7. Fully automatic digital display, which can replace manual density meters (specific gravity meters), density bottles (specific gravity bottles), and Abbe refractometers.
8. Chinese cultural operation, simple and compact, modular integration, fully automatic control and operation, flexible solutions.
