Kitchen and Housewares Reviews of Industrial Test Systems, Inc. Total Hardness Water Test Kit bottle of 50 testsCustomer Review: Gives a rough idea
The color matches on the side are a completely different shade than the colors produced from the test kit, making it pretty difficult to determine the hardness. 8 colors to match with grains per gallon values of 0, 2, 5, 7, 11, 15, 25, 58. With some difficulty you can probably get your color narrowed down to 2 of those.
