Unlike other water test kits on this buying review, this product leverages the drop count titration technique to test the concentration of calcium and magnesium ions in your water.

Drop count titration technology is more accurate than comparing color changes on a chart. You don’t have to budget for any extra item once you purchase this water testing kit.

This water test kit makes it possible to tell whether you’re experiencing carbonate or non-carbonate hardness. Carbonate or temporary hardness signals magnesium bicarbonate concentration, which often manifests in scale buildup in water heaters and boilers. On the other hand, non-carbonate or permanent hardness comes from calcium and magnesium chlorides, sulfates, and nitrates.

This product allows you to carry both carbonate hardness non-carbonate hardness tests to get the total hardness. You can use the alkalinity parameter to measure these two levels of water hardness. An alkalinity value that is less or equal to the hardness represents carbonate, while greater values represent non-carbonate.

What Should You Look for When Buying the Best Water Test Kit?

Laboratory Fees and Return Shipping Charges

The results obtained from most of these test kits are for informational use only and may note suffice for advanced analysis. In that case, manufacturers may offer extensive sample analysis. Watch out for the costs associated with advanced analysis, such as lab fees and return shipping charges. A brand that provides a waiver of these expenses makes the best go-to option.

Type of Water Hardness

If you are drinking from hard water, you should buy a test kit that measures different water hardness levels, including carbonate and noncarbonate. Getting an accurate measurement of these two levels makes it possible to tell the total water hardness. Be wary of test kits that don’t indicate whether you’re experiencing permanent or temporary water hardness minerals.

Technical Support

You would want a brand that gives you technical support, especially if the test technology is a bit specialized, such as drop titration. The support team should be knowledgeable and ready to answer your concerns, especially if your tests show inconsistent results. In that case, watch out for a brand with 24/7 customer service.

Factors to Consider Before Buying a Water Test Kit


All the test kits reviewed on this buying guide come at relatively affordable price ranges. Even so, you may have to pay a higher price for kits that offer nearly 20+ testing parameters. Also, kits that use a meter scale may likely cost more than color-coded options. Either way, settle for an option whose price reflects the quality, accuracy, and performance.


The testing parameters on each product are for varying contaminants. It will help if you get a home-based test kit whose parameters test for up to 20 prevalent contaminants in city and well water sources. Moreover, some parameters such as alkalinity and bacteria should have at least two test strips for counter checking result consistency. Even so, some products are ideal for individual water source applications—for instance, a test kit dedicated to well water only.

Testing Procedure

Testing the parameters in your water isn’t something that you do daily. Moreover, most people who test their water using home-based kits probably do it for the first time. Watch out for a product that has a simple testing procedure outlined in the user manual or instruction videos. The color code chart should also be easy to use, even for people who sometimes experience color blindness. Most importantly, all the components required for running successful tests should come with the packaging, including chemical reagents.


A home kit that takes more than 10 minutes to show results in color changes will probably give you false information. Go for products that guarantee instant results, whether you’re reading it from a meter scale or color code. The best thing about instant results is that they are often accurate and free from secondary pollution. You should also avoid placing the test strips on any surface before reading the results, as this can cause inconsistencies.


Lastly, what would you do if your test strips don’t show any color change or give inconsistent results for a single parameter? It could be because you’re following the wrong testing procedure or the test kit is defective. Watch out for manufacturers who give up to a one-year warranty to cushion you from quality inconsistencies.

The Bottom Line

Testing your drinking water at least every six months is the surest way of keeping your loved ones safe. Home-based test kits are relatively affordable. Moreover, some brands come with a water knowledge handbook that teaches you how to improve the purification systems according to EPA standards.
