testo measurement top tip #2
Did you know that water can effect the temperature of cooking oil?
If there is still water in the oil, this will significantly augment the display values. If bubbles are still coming out of the fat, water is still present. If it is not entirely certain when measuring if water is still present, we recommend repeating the measurement after one minute. If the second reading is lower than the first, there is still water in the oil, and further measurements should be taken at five minute intervals until the reading is constant.
