When we tested the known solution, 5% white vinegar, its accuracy was within the expected range. The ONLY downside to this item is the lack of a waterproof case. We bought this item to replace the first meter we bought. I will publish a separate test report on the yoyomax floor measuring device. Please make a waterproof case for the device intended for liquid and moisture testing.
