Hach Drop Count Hardness Test Kit

Knowing your water's hardness is the first step in sizing a softener or troubleshooting scale, and the Hach Drop Count Hardness Test Kit makes that measurement refreshingly simple. Using EDTA titration with a bulk powder reagent, you simply count the number of drops required to change the solution color, then read off the total hardness concentration. There are no meters to calibrate, no batteries to fail, and no learning curve, just a clear, repeatable color endpoint.

Practical testing for professionals and homeowners

Drop-count titration is a proven, dependable method for measuring total hardness in the field or at the bench. It tells you how much calcium and magnesium your water carries, the two minerals responsible for scale on fixtures, reduced soap lather, and shortened appliance life. This kit is rated for approximately 100 tests, making it economical for ongoing monitoring rather than a one-time check, and its modest 0.63 lb weight means it travels easily in a service bag.

• Measures total hardness by EDTA drop-count titration
• Color-change endpoint is easy to read with no instrumentation
• Bulk powder reagent supplies roughly 100 tests per kit
• Ideal for verifying softener performance and right-sizing equipment
• Compact and portable for service calls and on-site checks
• No calibration or batteries required for dependable results

Regular hardness testing helps homeowners confirm a softener is regenerating properly and exhausting its resin on schedule, and it helps installers accurately size new equipment before a job begins, avoiding undersized systems that break through early or oversized ones that waste salt. Testing both the raw feed water and the softened output is a quick way to verify a system is doing its job. With consistent, instrument-free results test after test, this Hach drop-count kit is a smart, low-cost addition to any water treatment toolkit, whether you are a professional installer or a homeowner keeping tabs on your own supply.

Keeping a hardness kit on hand also makes it easy to catch a softener that has stopped regenerating before scale and hard-water symptoms return, saving you from premature appliance wear. Affordable, accurate, and built for repeated use, this drop-count kit is the kind of basic diagnostic tool that pays for itself many times over.
