ZenTest® PH60S-Z Smart Spear pH Tester Kit

5.0 out of 5 starsUse for soil testing blueberries. Works great, well made, easy to use. Accurate

I use this meter to monitor the Ph of soil for growing blueberries. Blueberries require a very acidic soil and it’s hard to maintain an acid soil for them so constant amendments are added to the soil to acidify it. This meter works flawlessly to spot check soil to know if it’s acidic enough or not in grow pots. Also use it to monitor soil after we have treated it to make sure it’s moving in the right direction. Treated soil takes 6months to a year to get ready before planting. I check the soil in multiple spots once a month. Much better than taking sample into the local extension office to check my soil. Really easy to use and calibrate. I really like that you can calibrate it and know your results will be accurate.
I will mention I paid the extra for the Bluetooth version, however the app is lacking and not very useful for logging data. Also the backlit digital screen is all you need. To much hassle to look at your phone for the same results in the meters screen.
If you using for plants. Stop searching and buy this meter. I have used the $20-50 meters, litmus paper, and the kits that you mix powder with the soil. All a waste of time compared to this meter. And they are super inaccurate.
