The Hydrion Water Hardness tester will tell you if your water needs treatment, and give you an estimate of the amount of treatment required. And then it will enable you to tell if the treatment has been effective.
The test paper makes this vital information available to you in minutes, and eliminates the need for laboratory facilities, special equipment, or technically trained personnel to test the water. With this convenient dispenser, you can take a reading at a moment's notice.
The Hydrion Water Hardness Tester consists of two different 15 foot rolls of test paper, each one with its own calibrated color chart. One paper gives readings at 0-5-10-20 grains per gallon of hardness as calcium carbonate. (5 grains per gallon represents moderately hard water.) The other paper is for hard water and gives readings of 10-20-30-50 grains per gallon of hardness. These rolls come in a convenient dispenser and a rugged carrying/storage case.
