Description This temporary water hardness test kit from Vivreau is designed to test the concentration of calcium carbonate in your water supply. This test is perfect for any espresso machine and will tell you if the water tested is safe to use with your equipment. Pasquini Espresso Co. recommends water with under 50ppm of calcium carbonate to be safe for use with espresso machines. If you completed the below test and your water is above 50ppm then a water system like the Vivreau Purity C Quell ST or BWT Bestsave S should be used to reduce the calcium carbonate to below 50ppm. Specifications Dropper bottle of testing solution Measured beaker with a 5ml marking line Conversion chart Instructions (Product Image Includes Instructions) 1. Fill beaker to 5ml with water you wish to test. (Rinse and dry beaker before each test to ensure no contaminants are present from other water sources) 2. Add 1 x drop of testing solution and swirl around. Water should turn light purple. 3. If water turns yellow on the first drop and does not turn purple, then the water is soft and has a calcium carbonate level of under 17.85ppm. 4. If your water turned purple after the first drop, continue to add 1 x drop of testing solution at a time and swirl for 2-3 seconds in-between each drop. 5. Water will eventually turn from purple to yellow as drops are added. 6. Count the number of drops, including the first drop, it took to turn the water yellow. Multiply the total number of drops by 17.85. 7. This number is your calcium carbonate level. (e.g. 5 drops = 89.25ppm calcium carbonate) Questions on this item?Contact us.
