For the Most Accurate Home Testing, Use Multi Reference!

* Due to the Alk being too low, this does not work as a Trident calibration solution. Will resort in error codes for Alk.

With Fauna Marin Multi-Reference Solution, you can test your home test kits under accurate conditions. The Reference Solution is the first to be based on a saltwater matrix and is quality tested using Fauna Marin’s ICP-AES testing machine.

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
• Checkingan expired test kits accuracy
• Calibrating your refractometer

Example:

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
