Check out the first picture below. We are on a well with horribly hard water. But we have a water softener. The strips closest to the camera are the well water prior to running through the softener, the strip in the back is after running through the softener. The colors are easily readable - the pads in the front are brown, the water is VERY hard. The pads in the back are green, the water is very soft, so my softener is working. (Note - there are 2 color pads on each strip - those are just to ensure that the strips are functioning. No matter what color the pads turn, they must match on both color pads.) The price is super reasonable - $10. Also, the kit comes with 200 strips, which is probably going to be a lifetime supply for me... Review: Works Exactly as Needed! - I love these! We live out in the country with well water, so we have hard water and a water softener. We use these to tell if our water softener has re-generated or not. They work great, come in great packaging, and last a long time! Worth the money if you have well-water and a spotty water softener. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5DLWK43 | | Best Sellers Rank | #3,164 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2 in Lab Viscometers | | Brand | WEAQUA | | Brand Name | WEAQUA | | Customer Reviews | 4.5 out of 5 stars 1,140 Reviews | | Included Components | 200 x Water Hardness Test Strips, 1 x Sample Cup, 1 x User Manual | | Item Weight | 2.08 ounces | | Manufacturer | WEAQUA | | Material | Test Strips | | Material Type | Test Strips | | Model Number | Water Hardness 200 Strips | | Number of Items | 1 | | Part Number | TDS ECO (1 TDS Meter) - 3 | | Recommended Uses For Product | Water Hardness Test | | Unit Count | 200 Count | ## Product Details - **Brand:** WEAQUA - **Manufacturer:** WEAQUA - **Number of Items:** 1 - **Recommended Uses For Product:** Water Hardness Test - **Unit Count:** 200 Count ## Images ![DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Image 1](https://m.media-amazon.com/images/I/71yey-kkCKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to Read and Accurate - I Can Actually See the Difference *by B***T on August 30, 2026* These strips worked perfectly.
