Test kit reagents can lose their effectiveness due to storage time and conditions. This can lead to less than accurate testing results. Checking test kits against a calibrated standard solution can avoid these inaccuracies.

Multi-Standard
Mineral standard for test kits
Multi-Standard is a calibrated standard solution, prepared under laboratory conditions, that can be used to check the accuracy of test kit reagents for values of calcium, magnesium, potassium and KH/alkalinity.

NP-Standard
Standard for nitrate and phosphate test kits
NP-Standard is a calibrated standard solution, prepared under laboratory conditions, that contains consistent  values for both nitrate and phosphate and can be used to validate the precision of test kits.
