Last week I could barely see the results, now it is all gone. Leave this one, buy one with a brand name. ### ⭐⭐⭐⭐⭐ Works great! *by A***N on 21 October 2024* When I first tried it out the readings weren't very accurate and it errored out when testing tap water. I replaced the battery and it works great, very consistent. The good thing is the batteries are inexpensive, worth it. ## Frequently Bought Together - VIVOSUN TDS Tester 3-in-1 TDS EC & Temperature Meter Ultrahigh Accuracy Digital Water Quality TDS Tester (Blue) - VIVOSUN PH Meter Digital PH Tester Pen 0.01 High Accuracy Water Quality Tester with 0-14 PH Measurement Range for Household Drinking, Pool and Aquarium, with ATC, Army Green - General Hydroponics pH Control Kit For A Balanced Nutrient Solution --- ## 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.co.uk/products/416390445-tds-tester-3-in-1-tds-ec-and-temperature-meter](https://www.desertcart.co.uk/products/416390445-tds-tester-3-in-1-tds-ec-and-temperature-meter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-10*
