I must rely on the manufacturer's claims at this point. It does however detect extremely small amounts of hydrogen and the temperature scale is correct when compared to my other thermometers. ### ⭐ doa, dead on arrival *by V***N on January 26, 2024* Two for two, both dead on arrival , plus had to order batteries for them. Unit would not come on , but the batteries got hot. So wasted money and time on batteries When I said two , one was a repacement ### ⭐⭐ No batteries *by W***A on July 10, 2023* It don't have any batteries and also no info on what battery should be installed in it ## Frequently Bought Together - Fishawk Digital Hydrogen Meter, High Accuracy Pen Type H2 Meter Water Quality Tester with ATC, LCD PH TDS Salt PPM Temp Tester Meter for Drinking Water Hydroponics Aquariums Swimming Pool - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - 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.pl/products/476335538-digital-hydrogen-meter-high-accuracy-pen-type-h2-meter-water](https://www.desertcart.pl/products/476335538-digital-hydrogen-meter-high-accuracy-pen-type-h2-meter-water) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-01*
