Being mains is stays on 24/7 unlike my other monitoring unit that is only battery powered so I try to keep it off. Use the Ph testing solutions to know how the unit reads. Both my units monitoring read under by 0.5.Doesn't have a good way to hang it up. Has a sticky tab that falls off from a U carriage. Needs a couple of slots to secure it easier with zip ties or hooks. But really like this small unit. Quick to react to water changes immediately. Like it. ### ⭐⭐⭐⭐⭐ Perfect *by B***Z on Reviewed in Canada on 23 August 2021* Has everything I need. Very accurate with large display. ## Frequently Bought Together - 2 in 1 pH & Temperature Monitor, pH Meter with Backlight Function, Dual Display 0.00~14.00pH °C/ °F Water Quality Tester pH Monitor for Water, Fish Tank, Aquarium, Hydroponics, Pools - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - VIVOSUN Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified --- ## 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.sk/products/276930641-2-in-1-ph-and-temperature-monitor-with-backlight-replaceable](https://www.desertcart.sk/products/276930641-2-in-1-ph-and-temperature-monitor-with-backlight-replaceable) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-07*
