Each time you want to use it you need to pour out a certain dose of the calibration powder to be used in combination with distilled water and pour it out when you are finished. However, in order to make it more effective, we recommend to use it in one packet, so that it is easier to use. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works *by C***R on 31 May 2026* Works ### ⭐⭐⭐⭐⭐ Good value *by M***L on 10 November 2025* Good value ### ⭐⭐⭐⭐⭐ works *by S***Y on 30 May 2023* works ## Frequently Bought Together - Nynelly 15 Pack pH Meter Buffer Calibration Solution Powder for Precisely Calibrate pH Meter, pH Tester Calibration Powder Packets, pH 9.18/6.86/4.01 - Distilled Water - 100% Ultra Pure Water (Blue) (1L) - Dr.meter PH Meter, PH Tester for Water 0.01 Resolution High Accuracy PH Meter for Water 0-14pH Range Digital PH Tester with Data Hold and Backlit Two-Color LCD for Hydroponics, Garden, Pool, Aquarium --- ## 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.tn/products/425585557-15-pack-ph-meter-buffer-calibration-solution-powder-for-precisely](https://www.desertcart.tn/products/425585557-15-pack-ph-meter-buffer-calibration-solution-powder-for-precisely) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-12*
