Bought the above some months back from aquastar and decided to open it today. Found out that the charts were missing. Is there any where to download the colorcharts online ?

The degree of hardness is determine by how many drop of reagent you have dropped which make the test tube of water under test change to endpoint color, hence no chart is needed.

thanks guys, the instruction booklet does indicate the no. of drops = 1/2/3 etc , however, when do we know which color intensity to take ? a diluted green or yellow can seem concentrated to some ppl, with at least a colorchart, at least i know with a certain number of drops, i am hitting the right color tone.
