Hand Refractometer 0 – 32% Brix

From £62.40

Refractometers are handheld, lightweight, portable instruments used to determine the concentration of water soluble fluids such as machine tool coolants and heat treatment fluids. The BRIX scale was actually developed for working with sugar related liquids (fruit juices, soft drinks, wine), but it is also commonly used for controlling the concentration of various industrial fluids.


Refractometers are very easy to use, first it is important to remember to calibrate the unit by placing a few drops of clean water on the prism and adjusting the screw on top until you get a reading of zero. Then place a few drops of coolant on the prism and hold the unit up to a light source. Look into the eyepiece and read the scale.


Remember, refractometers read on a Brix scale rather than actual percent. To get the actual percent, you must multiply the refractometer reading by your coolant’s refractive index (stated on product data sheet). If you are unsure, please contact our Technical Service Department.
