It gives you several useful readings in one device and is much more convenient than buying separate meters. The readings have been consistent for what I need, and the auto-calibration and temperature compensation make it easy to get started without a lot of messing around. The display is easy to read, and having the hold function is a nice bonus. For the price, I really don’t think you need to spend more unless you have a specific reason to buy a higher-end professional meter. This one gives you the important functions at a fraction of the cost. Definitely one of those purchases where you get a lot for your money. Review: Recommend. Much better than the ph strips - This product works as advertised. You have to calibrate it first using the provided ph packets but once you do that it is good to go and offers accurate reading. This product assembly and price range makes for a nice introductory ph meter as opposed to a more premium, and also costly, assembly, yet it is still so much better than a manual ph test strip. I would recommend this product to anyone looking for an affordable digital oh tester. I like the vivosun brand and the products they have offered so far. ## Features - Application: Ideal for residential or commercial use, water, pool, spas, liquid food, laboratory, aquaculture and hydroponics - Easy Calibration: Advanced technology makes the test result fast and accurate; LCD screen makes reading clearly - Features: Pocket size, lightweight, backlit function, high quality - ATC Function: With Automatic Temperature Compensation (ATC), adjust to water temperature and give pH reading almost instantly - What You Get: pH meter, user manual, 2 x 1.5V button cells (built in), 3 x pH buffer powders ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01M5IASHD | | Best Sellers Rank | #366 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Lab pH Meters | | Brand | VIVOSUN | | Brand Name | VIVOSUN | | Customer Reviews | 4.0 out of 5 stars 33,876 Reviews | | Included Components | Batteries included | | Item Highlight | ±0.01 pH Accuracy, ATC, Auto Calibration, Backlit LCD, Memory, Compact, UL Certified, for Hydroponics Aquarium Pool Drinking Item Highlight ±0.01 pH Accuracy, ATC, Auto Calibration, Backlit LCD, Memory, Compact, UL Certified, for Hydroponics Aquarium Pool Drinking See more | | Item Weight | 0.11 kg | | Manufacturer | VIVOSUN | | Material Type | ABS | | Model Number | 4316344538 | | Number of Items | 1 | | Part Number | 4316344538 | | Ph Range | 0.00-14.00 | | Sterility Rating | 0.00-14.00 | | UPC | 714119465581 | | Unit Count | 1 Count | ## Product Details - **Brand:** VIVOSUN - **Manufacturer:** VIVOSUN - **Ph Range:** 0.00-14.00 - **UPC:** 714119465581 - **Unit Count:** 1 Count ## Images ![Digital pH Meter 0.01 Accuracy Pen Tester for Water Hydroponics - Image 1](https://m.media-amazon.com/images/I/51oVdDBZlWL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: What do you use to clean electrode?** A: Instructions say to use distilled water to clean electrodes **Q: Would this be a good tool for an aquarium?** A: Sure it will read the Ph for your tank **Q: Does it work well for testing ph in a saltwater pool?** A: I don’t know anything about testing pool water but it will definitely give you the ph between 4.0-10 **Q: My pen has gone way out of calibration. 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 ### ⭐⭐⭐⭐⭐ Great value for a reliable meter! *by U***N on August 13, 2026* If you’re looking for an affordable way to check pH, TDS, and EC without spending a lot of money, this is a great option.

For $10 at time of order, you’re getting a meter from a reputable brand that won’t break the bank and does exactly what it’s supposed to do. Included in the package are a nice plastic storage case, extra batteries, and a set of pH calibration buffer powders (6.86, 4.00, and 9.18), which was a nice touch. Calibration was quick and easy and I’ve only needed to recalibrate about once every 3-4 weeks. Readings also seem accurate and consistent. My only real complaint is the build quality. It definitely feels made from cheap plastic and while the buttons are clicky, they still feel a little flimsy. Overall though, I’m happy with this purchase and can comfortably recommend it as long as your expectations match the price point. ✅ What I Like - Low-priced. - Gets the job done. - Comes with a decent plastic storage case. - Includes pH calibration buffers (6.86, 4.00, and 9.18). - Comes with an extra set of batteries. - Readings seem accurate and consistent. - Calibration process is simple. ❌ What Could be Better - Build quality could be better. - Feels made from cheap plastic. - Buttons feel a little flimsy despite being clicky. Final Verdict | ⭐️⭐️⭐️⭐️☆ Here is how I rate items: 5 ⭐️ = Completely exceeds expectations. 4 ⭐️ = Works well with minor concerns. 3 ⭐️ = Does the job, nothing special. 2 ⭐️ = Some things work, but lots of issues. 1 ⭐️ = Didn’t work well, not worth it. ## 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.kg/products/40679482-digital-ph-meter-0-01-accuracy-pen-tester-for-water](https://www.desertcart.kg/products/40679482-digital-ph-meter-0-01-accuracy-pen-tester-for-water) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-10-15*
