PH measurement is sufficiently accurate and very convenient. Also, you can always recal if you want. Salt measurement is crap. It was accurate when received but went south pretty quickly after use. --- ## 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.co.th/products/695830159-pious-ph-tester-digital-5-in-1-ph-meter-water](https://www.desertcart.co.th/products/695830159-pious-ph-tester-digital-5-in-1-ph-meter-water) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
