### ⭐ Good idea, but very poor design. Also terrible Quality Control
*by W***N on December 7, 2023*

If you want to measure the Ph of one container, and the EC of another seperate container, this is for you. If you want to measure the Ph and EC of the same container/liquid this will not work. When I measured the Ph and EC seperately this was spot on. However when I put both probes into the same container/liquid the EC would quickly go out of range and the Ph reading was way off. I suspect that there is an unwanted electric leakage current flowing between the 2 probes when in the same liquid, which is hosing the readings. This should have been caught by the Co. QC department. Bad desigh/assembly for sure.
