Ing even changes colors whenever the p h is dropped between acetic base or alkaline. Review: Easy to use meters for pH, TDS, EC, and temperature - Make sure you have distilled water when you use this or any other pH meter. Calibration is recommended before use and the probe needs to be rinsed with distilled water after use. The pH meter should be calibrated prior to use. As a test, I read the pH of a water sample before calibrating the meter. It read 7.22. After calibration, it read 7.10. Recalibration is not required under most circumstances, but the instruction pamphlet does tell you to mark the buffer solutions that you made so you can recalibrate later. Unfortunately, there is no mention of shelf life or storage conditions for your buffers. The powdered chemicals to make the buffers are included, but you're going to need 1 to 3 cups of distilled water to dissolve them in. After calibration, you're good to go and just have to follow the use and maintenance instructions. The pH meter takes a little while for the reading to stabilize. That's pretty standard for devices that test water. The second meter in this kit is for TDS (Total Dissolved Solids), EC (Electrical Conductivity), and temperature in °C and °F. The temperature function is probably the most useful feature of this probe. This probe is low maintenance, just requiring you to clean the electrode after use and replace the cap. As for cleaning the electrode, I just fold up a paper towel into a little point and twirl it around each electrode rod. If I were putting the sensor in something dirtier than tap water, I'd also rinse it off before drying it. Technically, I should probably be washing the electrodes with distilled or DI water after each use (that's from my previous experience with meters like this, not that the instructions say to do so), but for everyday noncommercial household purposes, I'm not going to be bothering to do that. Temperature is correct. TDS is at least in the correct ballpark although I have no way of saying exactly how accurate it is. I'm not sure about EC. The temperature reading changes continually, but the TDS reading will stay on the meter even after you remove it from the liquid which can make reading your result much easier. Overall, I'm happy with the ease of use and quality of these meters. Readings are accurate according to litmus paper and testing of the buffer solutions after calibration. I ordered this set because I'm getting into hydroponics and aquarium set-up and you really should know pH for both of those. ## Features - Digital pH Meter: It has a large range of -2.00 to 14.00, and the use scene is wider. Backlight display, the color of the display backlight of the pH meter will change according to the pH value, just like pH test strips - TDS/EC/Temp Meter: 3-in-1 digital water quality tester that provides accurate readings of TDS (Total Dissolved Solids), EC (Conductivity), and Temperature, professional, accurate, and precise 3-in-1 TDS/EC/Temp meter - Automatic temperature compensation: Both the pH meter and the 3-in-1 TDS meter have an ATC function, which can reduce the error caused by the change in solution temperature - Easy to use: Rinse the electrodes of the pH meter or TDS tester with pure water first, wipe dry with a cloth or filter paper, turn on the meter put it into the solution to be tested, and stir gently, wait for about 5 seconds until the reading is stable to obtain the test value - Wide Application: Ideal tester for any aquarium, aquaculture, swimming pool, spa, school laboratory, food & and beverage, drinking water, etc ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.9 out of 5 stars 24 Reviews | ## Images ![Digital pH and TDS Meter Combo, High Accuracy 0.01 Water Quality Tester and 3-in-1 TDS and EC Meter, PPM and µS Meter for Water, Practical Water Testing Kit - Image 1](https://m.media-amazon.com/images/I/61fdKleADNL.jpg) ![Digital pH and TDS Meter Combo, High Accuracy 0.01 Water Quality Tester and 3-in-1 TDS and EC Meter, PPM and µS Meter for Water, Practical Water Testing Kit - Image 2](https://m.media-amazon.com/images/I/71glzUxVUYL.jpg) ![Digital pH and TDS Meter Combo, High Accuracy 0.01 Water Quality Tester and 3-in-1 TDS and EC Meter, PPM and µS Meter for Water, Practical Water Testing Kit - Image 3](https://m.media-amazon.com/images/I/71focezWl9L.jpg) ![Digital pH and TDS Meter Combo, High Accuracy 0.01 Water Quality Tester and 3-in-1 TDS and EC Meter, PPM and µS Meter for Water, Practical Water Testing Kit - Image 4](https://m.media-amazon.com/images/I/71hwnu7KwCL.jpg) ![Digital pH and TDS Meter Combo, High Accuracy 0.01 Water Quality Tester and 3-in-1 TDS and EC Meter, PPM and µS Meter for Water, Practical Water Testing Kit - Image 5](https://m.media-amazon.com/images/I/71jKn9-MvfL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The backlight *by B***. on September 29, 2024* This thing is awesome the backlight.

For me, having a device that can test the ph and accuracy of the water you drink daily is essential. As soon as I received the package, I went straight away to test it. I found that my drinking water is ever so slightly above 7. It was a relief to prove that my water filter works as advertised. The reading also comes in a colored view. If the water was extremely acidic, the color of the display would be red. Since it was almost perfectly balanced, the color was blue. I like that the main device has this feature. I also tested the accuracy of the water. Turns out I have healthy filtered water by using the manual and the accuracy chart. I would have liked it better if the display was colored like the ph device, but that's merely my preference. Now that I have this kit, I can test everything that I drink. I plan to hold on to this kit as long as I possibly can. Everyone should know what kind of liquids they expose themselves to daily. My recommendation: buy it asap. If you learn something about what you drink, you give yourself information that can help you make better choices. 4/5 stars easy. ## Frequently Bought Together - Yewhick Digital pH and TDS Meter Combo, High Accuracy 0.01 Water Quality Tester and 3-in-1 TDS and EC Meter, PPM and µS Meter for Water, Practical Water Testing Kit - General Hydroponics pH Control Kit For A Balanced Nutrient Solution --- ## 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/527143244-digital-ph-and-tds-meter-combo-high-accuracy-0-01](https://www.desertcart.pl/products/527143244-digital-ph-and-tds-meter-combo-high-accuracy-0-01) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-30*
