SPECIFICATIONS

• Includes: 1 dropper of testing solution, 1 measurement beaker, 1 conversion chart

COMPATIBILITY

• Fits: any espresso machine with a brass or copper boiler that needs a water hardness check before setup or filter selection

PRO TIPS

• Run the tap until the water is cool before testing (hot tap water throws off the reading), then fill to the 5 mL mark and add drops one at a time while swirling, the color runs purple after the first drop and the test is done the moment it turns stable yellow. Overshoot by a couple of drops and you'll under-read your hardness.
• Use the included conversion chart to translate your drop count into grains or ppm before choosing a water filter cartridge, guessing at hardness is how people end up with a filter that's undersized for their actual water and scales the boiler early anyway.
