The accuracy of the tds I think is good, the thermometer takes a while to get to where it needs. It’s cheap and easy to read. Appears to be waterproof as well which is kind of essential but you never can tell the durability on some of the cheaper products. ## 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.sg/products/416390445-tds-tester-3-in-1-tds-ec-and-temperature-meter](https://www.desertcart.sg/products/416390445-tds-tester-3-in-1-tds-ec-and-temperature-meter) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-13*
