Originally I ordered the 'non' rapid tablets which aren't great. These rapid ones as soon as you put them in the test tube and shake for 1-5 seconds have dissolved and changed colour to read PH. Note- they are only refill tablets no kit included you will need that separately. ## Frequently Bought Together - Lovibond Phenol Red Tablets - 250 Pack - Professional-Grade Reagents for Digital Photometers| Reliable, Easy-to-Use & Accurate Water Testing - Certikin - DPD No 1 Chlorine Tablets | 250 Count for Photometer | Measures Chlorine, Bromine, Ozone | Long Shelf Life, Easy to Use | Suitable for Photometers, Multicoloured - Certikin - DPD No 3 Total Chlorine Tablets | Precise Dosing & Long Shelf Life | Photometer & Comparator Compatible | Eco-Friendly Chemistry | High Accuracy, Multicoloured, 250 Pack --- ## 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.ph/products/53490323-phenol-red-tablets-250-pack-professional-grade-reagents-for-digital](https://www.desertcart.ph/products/53490323-phenol-red-tablets-250-pack-professional-grade-reagents-for-digital) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-06-16*
