Ease to use. ### ⭐⭐⭐⭐⭐ Great product *by G***S on 11 April 2024* Easy to calibrate and use. Better than I expected with a much steadier readout result ### ⭐ Tester I purchased not accurate *by G***E on 14 March 2025* Have had this item for 10 months but unfortunately the readings are not accurate despite 2 battery changes and multiple calibrations. The temperature is reading at least 3 degrees below what it should be and ph readings about 4 above what they should be. It was with the new improved 2024 sensor head, but I would suggest further improvements needed. Now looking for an alternative product. ## Frequently Bought Together - YINMIK PH Meter, Digital 4 in 1 PH EC TDS Temp Meter for Water Hydroponics, Waterproof DWC PH and EC PPM Water Tester with Backlit for Nutrients Growing, Indoor Garden, Home Brewing, Pool, Aquarium - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - YINMIK pH Meter Calibration Solution Kit(4.00,7.00&10.01) with pH Electrode Storage Solution Kit,3 Bottles pH Calibration Buffer Solution and 2 bottels KCL pH Probe Solution for pH Meters --- ## 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.ie/products/502202645-yinmik-digital-ph-meter-4-in-1-ph-ec-tds](https://www.desertcart.ie/products/502202645-yinmik-digital-ph-meter-4-in-1-ph-ec-tds) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-15*
