How to Use This Calculator
  1. Take a refractometer reading from your machine sump coolant sample.
  2. Enter the coolant manufacturer's refractometer factor (concentration multiplier).
  3. Set your target coolant concentration (%) and total sump volume (L or gal).
  4. Review actual concentration, deviation from target, and how much water or concentrate to add.
  5. Re-test with the refractometer after adjustment to confirm concentration is correct.

What each input means

Refractometer Reading
Reading from the optical refractometer.
Coolant Factor
Coolant manufacturer's refractometer correction factor.
Target Concentration
Desired coolant concentration percentage.
Sump Volume
Current volume of coolant in the machine sump.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Refractometer Reading = 5.5, Coolant Factor = 1, Target Concentration = 7, Sump Volume = 50 = 4 input(s) provided
  2. Calculate Actual Concentration
    Actual Concentration
    5.5 = 5.5
  3. Calculate Difference from Target
    Difference from Target
    -1.5 = -1.5
  4. Calculate Water to Add
    Water to Add
    0 = 0
