I used it to test a newly purchased V8 water hydrogenator, but it couldn't generate any hydrogen in a distilled water, you need slight amounts of minerals for the electrolysis to happen, but once tested with the filtered tap water (PH 7.5) it showed me 1300 ppb, that actually is exactly what the spec of this hydrogenator said it would generate. it takes about 10 to 15 seconds to start showing hydrogen level, so be patient. Also give it a chance to settle down on a value. Overall this is a pretty good value and quality little tool to help you test your water! ### ⭐ DO NOT BUY! *by S***D on May 19, 2024* PROS: None.CONS: Most of the senses are completely off! For example, here it's attempting to read the water temperature, I know for a fact the water is 40°F (5°C), but this device constantly reports it as 70°F (21°C). Even after multiple calibrations, the temperature is off by 15° at best. This is absolutely unacceptable! On a digital device, if it's off by a single degree then it is not a trustworthy device.That was just the temperature, it cannot read pH levels, H2 levels or ORP levels correctly either. Even the pH levels are off by two points. When pH levels are off by one point, it's dangerous! This company needs to be investigated and this product needs to be removed from the listing immediately.BOTTOM LINE: Do not buy! ### ⭐⭐⭐⭐⭐ Best one I found on Amazon *by C***S on February 2, 2025* Works great. I have two. I measure the pH of my pee (trying to become internally alkaline to combat ) and another to measure the pH of my water and its ionization created by my hydrogen bottle. Used them everyday for a year now. Easy to read the screen, other screens too small and I returned those. ## Frequently Bought Together - GISNPA PH Meter, Digital 4-in-1 PH ORP H2 Temp Meter, PPB/PPM Meter with ATC, 0.01 Resolution High Accuracy PH Tester for Drinking Water - 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.it/products/595631679-gisnpa-ph-meter-digital-4-in-1-ph-orp-h2](https://www.desertcart.it/products/595631679-gisnpa-ph-meter-digital-4-in-1-ph-orp-h2) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-13*
