## Customer Reviews

### ⭐⭐⭐⭐⭐ Cumple su función
*by R***O on July 28, 2025*

Funciona bien, solo hay que calibrarlo la primera vez y ya se puede usar sin problemas

### ⭐⭐⭐⭐ Great All-in-One Tester, Just Handle It with Care
*by B***5 on July 19, 2025*

I originally bought this water tester thinking I might use it for our pool, but I actually ended up using it to test some of my cosmetic formulations. I needed something that could check pH and a few other things, and this little gadget has come in really handy. It’s simple to use, doesn’t take up a lot of space, and gives pretty quick results, which is perfect when I’m working on batches and need to check as I go.The screen is clear and easy to read, even in lower lighting, and I liked that it was ready to use right out of the box. It seems to give consistent, accurate readings, and I really appreciate the temperature adjustment feature. It takes out the guesswork when the room isn’t perfectly controlled.The only reason I’m giving it 4 stars instead of 5 is because it doesn’t feel very durable. The buttons are a bit soft, and it’s definitely not something I’d want to drop. It’s splash-resistant, but not waterproof, so I make sure to handle it carefully, especially around liquids. You’ll also need to recalibrate it occasionally, and for that, you’ll need to grab the calibration solutions separately.All in all, it’s a great little tool for the price. If you’re working on skincare, haircare, or anything else where water quality and pH matter, this is a solid option, just treat it gently and it’ll serve you well.

### ⭐⭐⭐⭐⭐ Very accurate and comes in handy for multi purpose uses
*by K***R on September 3, 2025*

Versatile and reliable tool designed for anyone who needs accurate water quality measurements. With its 6-in-1 functionality, it combines multiple testing capabilities—pH, PPM (TDS), EC, salinity, temperature, and ORP—into one compact device, making it an excellent choice for aquariums, hydroponics, pools, spas, brewing, and drinking water monitoring. The meter has a modern, handheld design that is lightweight and easy to use. The LCD screen is bright and clear, displaying multiple readings simultaneously for quick analysis. The body feels sturdy enough for both home and professional use, and the included ORP 222mV calibration solution is a thoughtful addition for maintaining accuracy over time. Accuracy is where this device truly shines. With its advanced sensors and simple calibration process, it provides highly reliable readings across all six parameters. The fast response time makes it especially useful for daily testing routines, whether you’re balancing pool chemicals, monitoring a hydroponic system, or ensuring safe aquarium conditions. This tester is designed with user convenience in mind. The one-button operation and straightforward calibration steps make it accessible even for beginners. Switching between measurement modes is seamless, and the waterproof probe ensures it can withstand repeated use in wet environments without issue. Few testers offer this level of versatility in a single device. It’s particularly useful for users who manage multiple water systems, such as hydroponics enthusiasts who also maintain aquariums or home brewers who need to monitor pH and TDS levels precisely. Its multifunctionality eliminates the need for multiple separate tools, saving both cost and storage space.
