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 | #36,842 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #6 in Substance Analysis Instrumentation | | Brand Name | WEAQUA | | Customer Reviews | 4.5 4.5 out of 5 stars (1,115) | | Item Weight | 2.08 Ounces | | Manufacturer | WEAQUA | | Manufacturer Part Number | TDS ECO (1 TDS Meter) - 3 | | Material Type | Test Strips | | Model Number | Water Hardness 200 Strips | | Number of Items | 1 | | Recommended Uses For Product | Water Hardness Test | | Unit Count | 200.0 Count | | Whats in the box? | 200 x Water Hardness Test Strips, 1 x Sample Cup, 1 x User Manual | ## Product Details - **Brand:** WEAQUA - **Manufacturer:** WEAQUA - **Net Quantity:** 200.0 Count - **Number of Items:** 1 - **Recommended Uses For Product:** Water Hardness Test ## Images ![WeAQUA DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Hard Water Testing Strips (0-25 gpg / 0-425 ppm) - Image 1](https://m.media-amazon.com/images/I/810KR0QzV6L.jpg) ![WeAQUA DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Hard Water Testing Strips (0-25 gpg / 0-425 ppm) - Image 2](https://m.media-amazon.com/images/I/718-FfstHFL.jpg) ![WeAQUA DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Hard Water Testing Strips (0-25 gpg / 0-425 ppm) - Image 3](https://m.media-amazon.com/images/I/71VDq5UqV1L.jpg) ![WeAQUA DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Hard Water Testing Strips (0-25 gpg / 0-425 ppm) - Image 4](https://m.media-amazon.com/images/I/71ZMdY67MIL.jpg) ![WeAQUA DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Hard Water Testing Strips (0-25 gpg / 0-425 ppm) - Image 5](https://m.media-amazon.com/images/I/71gyBlqZBKL.jpg) ## Frequently Bought Together - DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Hard Water Testing Strips (0-25 gpg / 0-425 ppm) - WeAQUA Water Hardness Test Kit - DoubleCheck 50 Strips - Hard Water Testing Kit – Tests Calcium & Magnesium (0–425 PPM) – for Tap, Well, Drinking, Pool, Spa & Dishwasher - 2024 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(°C,°F) Meter - 0-9990ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/655023456-weaqua-doublecheck-water-hardness-test-kit-200-strips-with-sample](https://www.desertcart.pt/products/655023456-weaqua-doublecheck-water-hardness-test-kit-200-strips-with-sample) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-03*
