7 in 1 Water Quality Tester Pen Meter for Pools, Drinking Water Aquariums hydroponic Cooking Tester Measure Water by 7 parameters: PH/TDS/EC/ORP/S.G/Water Salinity/Temp

The media could not be loaded. I recently purchased the Water Tester PH Meter, and I couldn't be happier with its performance. The quality of this device is evident right from the moment you hold it. It feels sturdy and well-built, instilling confidence in its durability.When it comes to performance, this PH meter truly shines. It delivers high accuracy with a 0.01 PH measurement range, making it perfect for a wide range of applications, from testing household drinking water to maintaining the water quality in my pool and aquarium.One of the standout features is its automatic temperature compensation (ATC), which ensures that the pH readings remain accurate even in varying temperature conditions. This is crucial for obtaining reliable results.What's more, this PH meter offers fantastic value for money. Its accuracy and ease of use make it a valuable tool for anyone concerned about water quality. It has already saved me time and money by providing precise readings, preventing any guesswork.Speaking of accuracy, I was pleasantly surprised when I compared its readings to traditional strip pH paper. The results were consistent, with a margin of plus or minus 1. But what truly impressed me was how it solved a specific problem I had with my countertop RO water system.My RO system had always indicated that it released water at 12-14 TDS, and I relied on traditional strip pH paper to check the pH levels. However, it was a hit-and-miss process. Then, I decided to put this PH meter to the test.I was thrilled to find that it was not only easy to use but also incredibly accurate. It confirmed its pH readings matched those of the strip pH paper. Knowing that I can trust this meter's readings gives me peace of mind about the water I use.In summary, the Water Tester PH Meter is a top-notch tool that delivers quality, accuracy, and value for money. It has made water testing a breeze, and it even solved a specific problem I had with my RO system. I highly recommend it to anyone in need of a reliable pH measurement device.

Works well. Holds calibration. Accurate.

The problem with this product is NOT the product. It is the documentation! Written in pure Engrish, the purchaser is left to sort through a tiny sliver-like instruction manual that provides rough guidelines at the very best. "Bringing you safe life pleasure." What? Okay, so when do I need to calibrate, and when do I NOT need to calibrate? What are good readings, and what are bad readings for drinking water? Nothing like that, just a very rough set of rudimentary instructions (on-off, hold, etc). Please, just hire for $30 someone who can speak fluent English, with proper grammer, and re-write the instructions..... PLEASE!

I was excited about this product.... Untill i got it.The directions seemed to be written by AI.Completely incomprehensible. I had to go onto YouTube to find a calibration video since I had never done it before. The instructions were useless.But I found a video and matched it up best I could with the directions the meter came with. I did the calibration correctly according to the written instructions that came in the box.But every time I tried to test any sample of water, the readings were all over the place. Nothing consistent or accurate. I did everything right. Making sure to wash the tip off with distilled water and such. Nothing helped..I even decided to do little experiments with two samples of distilled water in the similar ceramic cups.The ph readings of both cups was wildly different. And the number would jump several numbers if I swirled the meter in the water. Often the meter would time out and shut off before I got a stable number reading. The number would just rise and fall without reason.I even tried to take a reading of the calibration solution again. The 6.86 solution literally has a ph of 6.86. That's the point.Nope.The meter was waaaay off and each testing of the solution was different.I tried calibrating the meter again, but it refused to.All in all, this was a complete waste of money. No way of telling if any of the ph readings are correct.I'm gonna go out and get pH test strips. The are less accurate but more consistent.Don't waste your time on this product.

Works fine. Scary results on what we think is safe drinking water.

Alright

Inconsistent in PH reading. Not so easy to calibrate. It was very cheap, so I can't expect much. I trashed it because an incorrect reading is worse than no reading. I bought a different brand and high quality with high reviews for $99 and very pleased with it.

Great gift!!! For my friend ! Save them all !
