This simple and accurate test lets you measure your water hardness in seconds, helping you protect your equipment and fine-tune your coffee extraction.

Each test strip quickly reveals water hardness levels by changing color, giving you a clear indication of whether your water is soft, moderately hard, or very hard. With a quick dip and a one-minute wait, you'll know exactly what adjustments are needed for better-tasting coffee and longer-lasting equipment.
