Is there a way to calibrate it against an accurate test kit? I.e. just set the pH?** A: I second the answer but Alix. I thought it could be recalibrated against the standards they provide and I would be back to using the ph tool. Once it started to give me bogus readings I knew I had a new paper weight. I even bought 7.0 fluid so I could check it before each use so I knew the readings were correct. I have extensive experience calibrating thousands of gauges in a railroad machine shop to NIST and audited by the ARR annually. Knowing I have a good accurate tool is important to me. The quality of this tool is below the mark. I am surprised as I own VIVOSUN products that are more reliable so I thought I would give it a chance. It lasted almost a year for me. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by A***R on 12 June 2026* Very good piece of kit, excellent delivery. ### ⭐⭐⭐⭐⭐ Ok product *by M***N on 6 October 2025* Works well ### ⭐⭐⭐ Good but not enough buffers *by S***N on 19 June 2026* Does what it's meant to do BUT they should include MORE than one set of buffers. ## Frequently Bought Together - VIVOSUN Digital pH Meter, 0.01pH High Accuracy Pen Type pH Tester for Hydroponics, Household Drinking, Pool and Aquarium, UL Certified - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - VIVOSUN 18-Pack pH Meter Buffer Solution Powder, pH 6.86/4.00/9.18, pH Buffer Powder for Precise and Easy pH Tester Calibration --- ## 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.pt/products/333016960-vivosun-digital-ph-meter-0-01ph-high-accuracy-pen-type](https://www.desertcart.pt/products/333016960-vivosun-digital-ph-meter-0-01ph-high-accuracy-pen-type) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-08*
