How the testo 260 functions
The new, user-friendly testo 260 tester is used to
measure the quality of cooking oil electronically.
Colour signal lamps enable a prompt, clear
interpretation of the results.
Cooking oil, consisting of more than 27% polar
components, i.e. decomposition products, has a
drastically reduced quality and must be regarded as
spoiled. Deep-fried products in the oil take in fat and
also the decomposition products which the consumer
finds very difficult to digest.
Testo´s cooking oil tester is based on the
measurement of relative permittivity in the cooking oil.
The level of polar components in frequently used oils
increases to such an extent that they can be
determined using the measuring method mentioned
above.
