Refractometers are precision optical instruments used for measuring concentrations of substances in aqueous solutions. They work by using the principle of light refraction through liquids. Refractometers measure concentration and oil emulsion. Concentration will appear as the horizonal line on the brix scale.

Manual Refractometer

Metal working liquid refractometer. 

Industrial Fluid Testers are refractometers designed to provide a rapid, accurate method for determining the ratio and concentration of water soluble cutting fluids and other industrial lubricants.

Our Refractometer is designed to assist machine operators in maintaining the delicate water/coolant balance.

​Proper coolant mixtures reduce waste and tool worn while increasing feed and speed rates, improving the efficiency of your equipment.

Digital Refractometer

  • Compact size allows for portability and use indoors or outdoors. Weighing only 100g, it can be easily placed in a pocket
  • Measurements are easily made with one hand
  • The speedy performance of the PAL-1 is amazing. Simply put a drop of a sample on the prism and press the START key. The Brix value will be displayed in just 3 seconds
  • Wide measurement range (Brix 0.0 to 53.0%) allows it to work in measuring almost any fruit juice, food, or drink, such as soup, sauce, ketchup, tomato sauce, low-sugar jam, or marmalade.
  • Protection class of IP65. You can rinse off the sample by running the unit under water
  • Automatic Temperature Compensation
  • Temperature of the sample stage displayed with Brix reading
  • The PAL-1 can measure high temperature samples during the heating or cooking process (the measured Brix value will stabilize after taking a few repeated measurements)
