Digital Coolant Refractometers

Refractometers for cooling lubricants allow you to measure the concentration of a cooling solution by determining its refractive index. Our range of digital refractometers provides fast and reliable refractive index readings, which can then be converted into Brix or other concentrations automatically. Their intelligent design also makes them easy to use; place a few drops on the prism, press the button, and get a reading within two seconds!
