The AF Reference Solution is a professional-grade calibration standard designed to verify the accuracy of marine aquarium test kits and calibrate measuring devices (like refractometers and colorimeters). It allows reef keepers to confirm if irregular water parameter readings stem from inaccurate testing equipment or actual water chemistry issues.
What It Tests
The solution provides laboratory-controlled parameters to verify the accuracy of your home drop tests and probes for:
- Salinity
- Carbonate Hardness (KH)
- Calcium
- Magnesium
- Potassium
- Strontium
Why Use It
- Calibration: Quickly recalibrate refractometers to ensure your salinity readings are exact.
- Testing Confidence: Eliminates the guesswork when trying to identify if a low/high reading is a true tank problem or an expired/faulted testing reagent.
