I bought 2pcs KL-027, 6in1 water quality monitor, after 2 times calibrated, i put all electrodes into a glass of clean water, the 2 monitors gave DIFFERENT READING for pH and ORP of THE SAME WATER, please see the photos.
Then I switched the electrodes to other unit ad calibrated again, and still the 2 monitors gave different reading of the same water.
and it is NOT 6in1 monitor! ONLY 3in1 ! becase we need to change the pH and ORP electrodes everytime we want to check pH or ORP.
i reported this false reading to the factory, but they did not gave any help..
IF you buy only 1pc you will never know that your monitor is giving you the correct reading or false reading!
you need to have 2 monitor or other pH meter to compare the reading, so you will know which monitor / meter give you the correct reading.
