Refractometers

Refractometer

Refractometers are instruments designed to measure an optical constant called the refractive index, a characteristic of the sample  and the particles dissolved in it. This is defined as the relationship between the speed of light in a vacuum and the speed of light in a substance, it is a property of the material that is not different from the boiling and melting points, but that facilitates the final identification.

The measurement of the refractive index allows to make a graph that relates this property with the concentration of the sample, just need to know exactly how it varies depending on the amount of the species in the liquid.

Types of Refractometer a Lab May Need

Digital Salinity

  • Easy to use: only 1 drop of sample is needed, and the button is read immediately after 3 seconds. Digital display shows TDS/Brix (%) °C
  • Easy calibration: With 1 drop of water, press the “ZERO” button to return to zero. You can operate with one hand. The special induction tank is not easy to flow
  • Portable and exquisite, low power consumption, anti-loss design.
  • High precision measurement: The resolution is 0.01 and high precision sensor. Coffee concentration (TDS) and coffee sugar (Brix value) can be measured

Digital Brix

  • Automatic temperature compensation (ATC): 10 to 40°C (50 to 104°C)
  • Measuring time: approximately 1.5 seconds
  • Minimum sample volume: 2 metric drops
  • Light source: yellow LED
  • Sample cell: stainless steel ring and flint glass prism
  • Case material: l ABS
  • Chassis Classification: IP65
  • Battery: 1.5V AAA

Description the product
Brix refers to the measurement of the percentage of sugars and solids dissolved in a given weight of fresh plant juice. These solids include sucrose, fructose, vitamins, minerals, amino acids, proteins, hormones and other solids commonly found in a plant's juice. This RHB-05 is specially designed for liquid cutting tests. It can also be used to test the low brix solution.
Features:
 
High quality body construction
It uses only ambient light, which means no battery or power supply is needed
Easy to focus and calibrate
