Good product. Accurate readings & easy to use Software is not updated for this model

This was easy to calibrate and worked very well.

I'm NOT getting paid for this review or getting any kind of compensation/discount/free product! This review is based ONLY on my personal experience using it and running tests and comparisons. I'm happy to report that this YINMIK YK-S01E device is very accurate when comparing to BlueLab Soil/fluid pH Pen and BlueLab fluid pH the reading were identical across all of them. The ONLY negative aspect is that the probe tip is made out glass which makes it very fragile. When poking the soil be sure to use something else to poke a hole and then insert in soil!?! Try to find something that's about the same length as the probe but a little wider/thicker. I have been recommending this exact device to over 50 Growers who were looking for a reliable but affordable soil pH pen but they got a surprise because this device also reads fluid pH and just as accurate as some of the most expensive pH pens. Just don't forget to calibrate it once a month. Happy Growing! 🪴

J avais le bluelab soil a 300$ que j ai changer 2 fois en 1 an pis celui la fais la job en masse. Il va super bien

Better than cheaper versions, the YINMIK pH probe is an easy way to test soil pH. It comes with everything you need (except purified water) to calibrate your sensor for the first time. It also has a metal spearhead to poke into the ground while protecting the (very fragile) glass tip as well as a brush to clean the tip between each test. The associated app (iPhone or Android) is minimalist but functional. It connects the probe to your phone via BlueTooth while in the ground and records the pH and soil temperature measurement along with date and time of the sampling. The app also allows you to add notes about where the sample was taken. Future versions might improve this by reading and adding the geo tag data from the phone. It saves the information in a file that can be downloaded as an excel worksheet. An annoying nit is that the “Save Recording” button does not actually save the data until you press the “Disk” icon. The instructions are easy enough to understand, but clearly not written by a native English speaker. The box and foam insert is sturdy enough to serve as a convenient storage container for the probe, test solution packs, instructions, and accessories. Worth mentioning is that you can replace the probe if you damage the glass tip…

Works really well after you calibrate it pretty east to use still can’t believe my other ph tester is off by 2.8
