Brix refractometers are effective at measuring coolant concentration. Coolant’s primary purpose is to lubricate and cool the work surface and tooling. Each coolant works best for a given application at a recommended concentration of it to water. Monitor the initial coolant charge, then each day, as evaporation increases concentration at the sump level. Maintaining the recommended concentration is essential in order to prevent problems.

Frequently asked questions

Find answers to common questions about our products and services
  • This refractometer measures coolant concentration in metalworking applications. Coolant lubricates and cools the work surface and tooling, and each coolant performs best at a specific concentration-to-water ratio — this tool lets you verify that ratio is correct.

  • As coolant evaporates from the sump, the concentration of coolant relative to water increases. Checking daily allows you to catch and correct concentration drift before it causes problems with lubrication or cooling performance.

  • The Brix scale indicates the concentration of a solution, and this refractometer reads within a 0–32 Brix range. Before purchasing, confirm that your coolant's recommended working concentration falls within that range, as using a refractometer outside its designed scale will produce inaccurate readings.

  • This refractometer includes a locknut specifically for calibration, allowing you to adjust and lock in the calibration setting to ensure consistent, accurate concentration readings over time.

  • Those three features are available on the Specialist version only and are not included with this OPT32 model. This model does include a comfortable eyepiece, an easy-to-read bright scale, adjustable focus, a textured sleeve for easy gripping, and a carrying case.

  • Yes, a carrying case is included with this refractometer, making it easy to store and transport to different machines or work areas.

Key Features
