    • On point so far
Currently a few weeks after calibration, unit still measures ph and ec beautifuly

    • Easy to use
The VIVOSUN Digital pH and TDS Meter Kit is a must-have for anyone managing hydroponics, aquariums, or pools. Both meters are lightweight, easy to use, and provide accurate readings for pH, TDS, EC, and temperature. The 0.01 pH accuracy ensures precise water quality measurements, and calibration is straightforward. I found them fast and reliable, making water testing effortless. A great value for maintaining optimal water conditions with confidence! ... show more

    • Great 3-in-1 pH and TDS Meter
The Vivosun 3-in-1 pH, TDS, and Temperature Meter is a highly precise and reliable tool for measuring water quality. With a high precision of 0.05 pH and a +/- 2% accuracy, this pen-type meter ensures accurate readings, making it ideal for various applications such as hydroponics, aquariums, and drinking water. The three-in-one functionality is convenient and provides comprehensive water analysis. However, the device could benefit from a more robust design to enhance its durability. Overall, it's a great tool that delivers reliable results. Highly recommended for those needing accurate and easy-to-use water quality measurements. ... show more

    • Testing the Waters (Literally)
The VIVOSUN Digital pH and TDS Meter Kit is like the eager scout team for my yet-to-be-built hydroponics empire. I’ve only tested it on plain old water so far, but it works perfectly—quick, accurate readings without any fuss.

    • Horrific accuracy
So I bought this set wanting to try out actually tracking and adjusting my pH and EC of my nutrients for my little indoor hydro-farm. Like most people, I didn't want to spend a lot on my little hobby so I figured I would give this product a try as I actually enjoyed some other Vivosun products. I'll start with the TDS/EC Meter. It is actually decent and appears to be pretty accurate right out of the box. I've used it for a little while and it remains to be acceptably accurate so far without any issues. Good to go, this one I'm pretty happy with and will continue to use at least for now. Next I'm moving on to the problem child, the pH Meter. Wow. Where do I begin. I started off trying to figure out how to calibrate this little thing as the instructions drastically varied from all the calibration videos available online for it. Maybe they changed the method but once I figured out how it wanted to be calibrated I went through the steps and all was good. I tested it a number of times using various testing liquids and it was pretty spot on (at least within acceptable limits for my hobby, not anything that needs to be precise though). So I mixed up some of my nutrient solution, cleaned the pH and TDS meters as advised to in the manual and put them away safely. Fast forward 1 week, I pull out the pH meter and dip it into a cup of distilled water and it tells me that it has a pH of 10.3! Far from the value of 7 I was expecting to see. So I pulled out my other pH balanced liquids to test and every one of them was extremely off from what it should be. It completely lost ALL calibration after one use, and one week of storage. I'm sorry but that means I need to calibrate this thing every time I turn it on? And they only supply you with one set of calibration powder that isn't to be re-used? Absolute and complete garbage. The calibration costs for a year would be well into the hundreds a year for a $10 meter! Absurd. This is a product you should definitely skip buying. Buy yourself a 14-sided dice and give it a roll, it will give you a more accurate guess on your pH level than this thing every will. I would return it, but I was not thinking and threw away the packaging already. ... show more

    • Great PH meter. EC came non working
In following instructions for calibration, it was easy. Using the PH seems to be accurate. The EC meter on the other hand has not worked properly from the package. Even after replacing the battery, it doesn't want to turn on. It appears to have a faulty on/off button for the 2 times it did turn on, I had to hold the button. That being said, I'm not able to give my opinion for the EC meter function. ... show more

    • Don't let the price fool you, this (and calibration fluid) is all you need
I use this tester several times a day to dial in veg and flower nutes. I purchased a bottle of EC fluid to check and reset the tester's calibration from time to time, a great investment for my peace of mind. The bonus PH tester is also great. And I purchased a set of calibration fluids for that also. I just decided to buy two more of these sets incase I drop one into solution or whatever. I can't live without these, and the price of scoring a few backups is well worth the peace of mind. The comments I've read about the unreliability must come from people who refuse to follow the directions or can't be bothered to calibrate from time to time. ... show more
