Product description
Coolant refractometer Brix 0–32%
Optical eyepiece reading · Automatic temperature compensation ATC
Handheld refractometer for checking the concentration of water-miscible coolants and cutting fluids. Suitable for CNC machine operation and workshop fluid monitoring. Only a few drops of sample on the prism are needed for a reading.
Specifications and features
| Measuring scale | Brix |
| Scale range | 0–32% Brix (0–32 °Bx) |
| Temperature compensation | Automatic, ATC |
| Reading | Optical, through an adjustable eyepiece with an eye shield |
The compact, durable design makes regular checks at the workstation convenient. The padded case protects the instrument during storage.
Converting a Brix reading to coolant concentration
Check the factor and recommended concentration in the technical data sheet for the fluid in use. Do not assume that a Brix reading equals the percentage concentration of every coolant.
Taking a measurement
- Check the zero setting with clean water. Adjust the instrument with the calibration screwdriver if necessary.
- Apply a few drops of coolant to the clean prism and close its cover.
- Point the prism towards the light. Look through the eyepiece, adjust the focus and read the value at the boundary between the light and dark areas of the scale.
- Convert the reading using the factor for the coolant. Clean the prism after use.
Items included
- Brix 0–32% refractometer with ATC.
- Padded storage case.
- Calibration screwdriver.
- Dropper for collecting a sample.
Coolant monitoring in machine tools
Regular concentration checks help maintain appropriate cooling and lubrication conditions. These matter for machining quality and productivity, limiting tool wear and operator working conditions. Fluid monitoring also forms part of machine maintenance and helps prevent operating problems.
