Works quickly measuring PH within seconds. Solid read out. Had it tested and it is completely accurate. Pleasant surprise at this low a price point.

Works like it should, affordable

The device has an interesting set of pH estimates to program it, which does take a couple minutes but is well designed and yields reasonable accuracy. Good unit overall!

I start seedlings in rock wool which is naturally high in PH. Each year I soak the rockwool and test the PH until around 6-7. I’ve never really had to be perfectly accurate. I was ok with just being close.Upon opening the PH tester, I calibrated it with the packets and instruction that were in the box. Every single reading (7, 4 & 10) were right on the money. Then to test it further, I put in some PH down liquid into the 10ph cup. By measurement I added exactly enough to “supposedly” drop the PH from 10 to 5. Would it work? After stirring and waiting a few minutes, I tested the water with this PH meter, and it READ exactly 5.0. I was ok with “close enough” but this thing was perfect.A few days later I was going to the pet / fish store to pick up some crickets. So I decided to test this thing against a professional machine tester that they use to test their aquarium water. I tested my tap water which read 7.2. Taking the same exact water, I went to the pet/fish store and had them test the water through their professional machine. They got a reading of 7.1.Bottom line, this thing is REALLY good and the most accurate PH meter I’ve ever had.

Works great! Great value. Highly appreciated

garbage product. First one broke in a matter of weeks. the replacement didn’t work right out of the box, but I didn’t try it until after the return window ended.

I was pleasantly surprised by how easy it was to set up and use. It was a little annoying getting all the powder to dissolve for the 4.0/7.0/10.0 solution tests, but easy to calibrate after that, and has been working great ever since.The display light turns off a little more quickly than I'd like, but that's a minor inconvenience at best. I appreciate that it gives me pH and temperature.

Reevaluated after 1 year….This PH meter comes with calibration packets and instructions. I used it out of the box and checked accuracy with our pool supply vendor and the numbers were accurate. I did not need to calibrate but a year later I found this impossible to calibrate to 7.0PH so not the best option over time. I was having a difficult time reading the test strips for my small above ground jacuzzi so I purchased this meter. It has helped me to keep the water PH levels where they need to be until I lost confidence and started a calibration. I also noticed some mold forming around the sensor after following directions to keep the sensor storage cap moist. It is a great value but it started to give inaccurate readings after a year of use and calibration did not work as instructions show. I do not need the temperature function but this works well.
