The FOM 330 oil testing device easily, quickly and reliably determines the quality of your oil. To do so, it measures the so-called „Total Polar Material“ (TPM) content in the oil and shows its value as an accurate percentage. The clear alarm via the coloured top alarm light makes it even easier to evaluate the quality of the oil. So you always know exactly when to change your oil. The FOM 330 frying oil tester prevents the direct exposure of your hand to the hot oil. To optimize the benefits of the FOM 330 combine it with the VITO oil filter system.
