Multi Reference Solution is ideal for:
Testing the validity of new test kits
Verifying results after unexpected test results
Testing kits that were stored for a long time
Checking an expired test kit’s accuracy
Calibrating your refractometer
Measurement of the reference solution with a magnesium test gives you a result of 1,000 mg/L.
The reference solution however contains 1,314 mg/L
The ratio therefore is: 1,314 mg/L : 1,000 mg/L
The correction factor is noted on the magnesium test
A later measurement with this magnesium test results in the aquarium water: 1,300 mg/L
Calculation: 1,300 mg/L * 1.314 = 1,708.2 mg/L
