I’ve used it for pool maintenance and general water testing, and both meters have been simple to operate and easy to read thanks to the clear digital displays. The pH meter responded quickly and gave consistent readings after calibration. I also liked having the separate TDS/EC meter included, since it makes it convenient to monitor multiple water conditions without needing additional equipment. The compact pen-style design is lightweight, portable, and easy to store between uses. Another thing I appreciated was the straightforward calibration process and the included instructions. The readings stabilized fairly quickly, and the hold function on the TDS meter is a helpful feature when testing samples in smaller containers. Overall, this kit offers good value for the price and works well for anyone needing basic digital water testing tools for pools, hydroponics, aquariums, or household use. Accurate, convenient, and easy to use. Review: High accuracy and color-coded—perfect for well-water monitoring! - My husband originally purchased this set last month so we could keep a closer eye on the water quality for our plants. We are on a well, so having a consistent way to check the water quality is essential. These meters have been surprisingly accurate and very easy to read, which has taken all the guesswork out of our routine. One of my favorite features—especially as someone who isn’t a pH testing expert—is that the two meters are different colors. It sounds small, but having them color-coded makes it so much easier to grab the right one at a glance! In terms of functionality and sturdiness, the pens feel well-made and durable. The caps have a tight seal, which is important for protecting the sensitive electrodes from drying out between uses. The digital screens have great color accuracy and clarity, making the numbers pop even if the lighting in the greenhouse or kitchen isn't perfect. For the price, you get a lot of accuracy and peace of mind. ## Features - Application: Great for all home and laboratory TDS & pH testing applications including aquariums, swimming pools - PH Meter: Full measurement range of pH 0 - 14, reliable and quick readings - 3-in-1 TDS Meter: Measurement Range 0-9990ppm, 0-9990µs/cm; Accuracy ± 2%, 0.1- 80.0°C, 32.0-176.0°F; Note: This meter can't test sea water - Features: Comes with protective case; Lightweight, handheld design for portability and convenience - Included: PH meter, 3-in-1 TDS meter, 3 calibration buffers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XKMH86J | | Best Sellers Rank | #715 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Lab pH Meters | | Brand | VIVOSUN | | Brand Name | VIVOSUN | | Customer Reviews | 4.1 out of 5 stars 24,492 Reviews | | Included Components | Test pH, TDS, EC & Temp Value | | Item Weight | 0.1 Kilograms | | Manufacturer | VIVOSUN | | Material Type | Plastic | | Model Number | 4336465266 | | Number of Packs | 1 | | Part Number | 4336465266 | | Ph Range | 0-14 | | Recommended Uses For Product | Aquarium, Home Water, Swimming Pool, Water Test | | Sterility Rating | 0-14 | | UPC | 615435160962 | ## Product Details - **Brand:** VIVOSUN - **Manufacturer:** VIVOSUN - **Ph Range:** 0-14 - **Recommended Uses For Product:** Aquarium, Home Water, Swimming Pool, Water Test - **UPC:** 615435160962 ## Images ![Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified - Image 1](https://m.media-amazon.com/images/I/61saEhctTWL.jpg) ![Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified - Image 2](https://m.media-amazon.com/images/I/712pP2mIVlL.jpg) ![Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified - Image 3](https://m.media-amazon.com/images/I/71kaajfejPL.jpg) ![Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified - Image 4](https://m.media-amazon.com/images/I/71-3ks3mZ8L.jpg) ![Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified - Image 5](https://m.media-amazon.com/images/I/71g2DZAc0lL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: I have purchased 2 of these, why are they so inaccurate?** A: If you calibrate ANY PH meter using the mix it yourself "calibration" solutions, accuracy will be impossible. I just purchased this meter set, and discovered the distilled water I use was ph4 and below! I have the "other" style cheap meter, that has proven very stable for me, and after checking it in GHP 7.0 calibration solution, used it to test the accuracy of this relentlessly poor example of a ph testing system. First off, the solution instructions make no mention what the ph of the distilled water needs to be. My 4.0 water mixed with the 4.0 and 6.86 powder, resulted in a solution of 3.3 and 6.0 instead, so IMO, the MIY calibration solutions are a joke, as are ph meters that calibrate on the 6.86 standard instead of 7.0. **Q: If i use a 7.0 calibration solution will the automatic calibration be off by .14 since it comes with a 6.86 calibratind powder?** A: Yes! I recently calibrated with 7.0. Prior to calibration, it read the 7.0 solution at 7.0, calibrated with 7.0 solution it now reads 7.18. Find the correct calibration solution **Q: If my tap water is between 6.5 and 7.0 ph do i need to add the ph up and down liquid i bought for indoor cannabis grow? What about ppm?** A: If you’re growing in soil 6.5 is perfect if you’re growing in Hydro/water do you want to be around 5.8 say you’re at 7.0 PH I would just add a couple drops per gallonTo get it down two around 6.5 **Q: If I choose EC, does it retain the setting after power cycles?** A: Yes, but my meter randomly switched back to TDS. The "EC" does not show a decimal, and the numbers are too close to TDS. If you don't pay attention, you will hurt your plants. Do not purchase. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A must have for that color blind person wanting to keep up with their ph reading! 👍👌 *by A***R on May 18, 2026* 5 Stars — Convenient and Accurate Water Testing Kit This VIVOSUN digital pH and TDS meter kit has been a very useful addition for checking water quality and monitoring pH levels.

I’ve had to leave it in a cup of whatever what I’m measuring and walk away for 30 mins to get a true reading that matched my master API kit. ## Frequently Bought Together - VIVOSUN Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - General Hydroponics CALiMAGic 1-0-0, Concentrated Blend of Calcium & Magnesium, Secondary Nutrient Deficiencies Helps Prevent Blossom End Rot & Tip Burn, Clean, Soluble, 1-Quart --- ## 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.pl/products/42468543-digital-ph-and-tds-meter-kits-0-01ph-high-accuracy](https://www.desertcart.pl/products/42468543-digital-ph-and-tds-meter-kits-0-01ph-high-accuracy) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-24*
