These test strips are calibrated to measure vitamin C from tablets that are dissolved in water but can be used for fruit, vegetable juices & even urine.
Vitamin C levels are shown as percentages where 0.01% equals 10mg/100ml & 0.1% equals 100mg/100ml. A 1000mg vitamin C tablet dissovled in 1000ml of water should give you are reading of 0.1%.
The Specifications tab shows a special color chart that shows what to expect if there is a lot of citric acid in the juice. The citric acid can make the strips look more purple than blue.
Fruit juices that claim 100% or more of recommended daily allowance (RDA) may read higher than the strips can measure so you might need to dilute the juice. e.g. 9 parts water & 1 part of juice will reduce the concentration to 1/10 the original.
