WeAQUA DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Hard Water Testing Strips (0-25 gpg / 0-425 ppm): desertcart.com: Industrial & Scientific

Review: My Tap Water Just Got Judged by 200 Tiny Strips - Packaging: Box arrived like it knew secrets. Inside: 200 strips, a sample cup, and the quiet promise of clarity. No wasted space, no confusing inserts—just the tools and a silent challenge: “Go ahead. Test everything.” Ease of Use: Dip. Wait. Compare. That’s it. No app, no calibration, no existential dread. The color chart is clear enough that even my skeptical cat could interpret it. I tested tap water, bottled water, rainwater, and one suspicious puddle. All judged. All catalogued. Accuracy: Ranges from 0–25 gpg and 0–425 ppm, which is basically the full emotional spectrum of water hardness. My kitchen tap scored a 0 ppm thanks to my water softener system. My rain barrel? A gentle 3. I now see my plumbing as well protected. Sample Cup: It’s small. It’s plastic. It’s perfect. I didn’t think I’d care, but it made the whole process feel official. Like I was conducting a ritual, not just dunking strips in water like a caffeinated raccoon. Visual Impact: Watching the strip change color is oddly satisfying. Like watching truth emerge from silence. I now test water before making tea, watering plants, or trusting a faucet. It’s become a lifestyle. Final Verdict: This kit doesn’t just test water—it reveals character. If you’ve ever suspected your tap water was plotting against your appliances, this is your moment. 200 strips means you can test with abandon, or ritualize each dip as part of a broader diagnostic lineage. Buy it. Dip it. Let the colors speak.
Review: Accurate results in a few seconds! - Excellent results! Hold strip under running water for 2 seconds and read. Very clear and precise results. The test strip on the left is before a Kenmore water softener was installed. The one on the right is after. huge difference!

## Features

- DOUBLECHECK - Each strip has two identical color pads. If the color pad colors differ after testing, it indicates that the test may not be reliable it should be performed again.
- SAMPLE CUP INCLUDED - Ensure the most accurate water hardness test results by using the included sample cup and filling the test water to the marked level.
- 200 STRIPS @ $0.04 EACH - The most strips available in the box with the lowest cost per test.
- ⁠INDIVIDUALLY WRAPPTED - For the longest shelf life possible the strips are packed in foils of 50. This prevents unused strips from going bad due to too much contact with air.
- DUAL TOP & BOTTOM DESICCANTS – Strips stay fresh for longer with two desiccants, one in the cap and one in the bottom of the bottle, to prevent moisture buildup.

### ⭐⭐⭐⭐ Plenty of tests
*by A***R on July 10, 2025*

I recently tried the DoubleCheck Water Hardness Test Kit 200 Strips, and it’s a reliable tool for monitoring hard water at home or in your aquarium. The test strips are easy to use—just dip, wait, and read the result quickly. They deliver accurate readings within one or two degrees of more professional kits, which is impressive for such a simple tool. What really stands out is the high strip count (200)—perfect for long-term use or frequent testing, and the color chart on the bottle makes it easy to interpret results. Plus, the compact packaging is ideal for storage. That said, the color matching isn’t flawless in low light, so I recommend testing under good lighting or comparing to a photo of the chart. Also, since the results are visual, subtle differences in water hardness can be hard to distinguish without a magnifier. Overall, I’m giving it 4 out of 5 stars—a dependable, cost-effective kit for anyone needing regular water hardness checks, with just a couple of minor usability quirks.
