Get this one *by L***M on 23 June 2025* Fantastic piece of kit. Well worth the money ### ⭐⭐⭐⭐⭐ Ac infinity ph meter *by M***N on 26 March 2025* Faster to read than essential ph pen ### ⭐ Not waterproof *by J***Y on 20 January 2026* Out of the box the item was well calibrated, reading 6.98 in the 7.0 test solution. I moved it to my fish aquarium and noticed the temperature was taking FOREVER (~5 minutes) to move from 70F to 80F and the pH readings would continue to move until it hit the right temperature. This was a major annoyance as that's way too long to stand there holding this pen. Given it's waterproof, I left in in a shallow part of the tank for 30 seconds while it adjusted to the temperature and when I checked it, it went to -2pH and is now stuck there. Will return due to the error. Would have likely returned due to how long it takes to register temperature regardless as my bluelab is near instant and that's what I'm used to. Everything was torqued down out of the box, but I opened afterwards and verified that water got in past the primary seal around the sensor. ## Frequently Bought Together - AC Infinity pH Meter PRO Kit, High Precision Digital pH Pen with ±0.01 pH Accuracy and Interchangeable Probe, Nutrient Test pH Meter for Water Hydroponics Plants, Gardening, Aquariums, Swimming Pools - AC Infinity CLOUDFORGE T3, Plant Humidifier 4.5L with VPD Humidity Controls, 10-Level Precision Vaporizer, Extendable Targeting Hose and No-Leak Seal for Grow Tents - 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.id/products/623686944-ac-infinity-ph-meter-pro-kit-high-precision-digital-ph](https://www.desertcart.id/products/623686944-ac-infinity-ph-meter-pro-kit-high-precision-digital-ph) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-06-03*
