Soil Three-way Tester, 3-in-1 Plant Moisture , Light and PH Meter ( PH not accurate !! )

Product description: amzn.to/3gmnFK2
We received today Soil tester from Vivosun three-way meter (Moisture/PH/Light).
PH does not seem to be very accurate. In this video we tested device sensitivity to PH measurements using water/vinegar solution. We mixed 2 table spoons of 5% Vinegar with gallon of water, which resulted in the solution with expected ~5.5 PH. More details about proportions could be found in the link: bit.ly/3ee4jW1
As video shows during application of the solution to our blueberry bush, devices showed changes in PH level, however it moved back to initial levels of PH equal to 7, shortly after liquid drained. It is hard to believed that PH will change back to original so fast, so preliminary conclusion PH functionality o the device not very useful

Why are you saying it isn't accurate? You used distilled water, but had the prongs in soil. Since the soil was more acidic, once you saturated the soil, it gave you an acidic reading. Next time you want to judge the accuracy of the meter, put it in a glass of distilled water. If you want an accurate reading for the PH, you first need to saturate the soil and when the soil is at an ambient temperature, stick the probes down to root level, then take a reading.

i thought they were pouring vinegar not distilled water

maybe your dirt has different ph

[@DickWigglin]

​@@bv1199 it probably does, since I don't add vinegar to my water.
