French fries, chicken nuggets or donuts: Fried food tastes good and is popular all over the world. For consistent quality of fried food, a regular exchange of the cooking oil is necessary. But beware: If the oil is changed too late, the oil is already contaminated by degradation products, and the flavour suffers. Changing the oil too early, on the other hand, has a noticeable effect on costs, especially in view of the steep rise in the price of vegetable oil.

With the cooking oil tester Testo 270 you can determine the quality of the cooking oil with a simple measurement - and thus the ideal time to change it. In this way you save oil – and costs – ensuring a consistently delicious frying flavour.

The right frying oil test
In contrast to a cooking oil test strip, measurement using a cooking oil tester is more intuitive and reliable, above all providing reproducible, comparable measuring values. A dye is applied to a cooking oil test strip and this changes colour accordingly in contact with the oil. Comparison with a table enables you to know how the quality of the oil is doing. However, because cooking oil strips measure the free fatty acid content and this varies during frying, caution must be exercised here.

How do I test frying oil with the Testo 270?
The frying oil test is extremely easy with the testo 270 cooking oil tester:

  • Remove the fried product and wait until there are no more bubbles visible in the oil.
  • Switch on the cooking oil tester.
  • Immerse the cooking oil tester in the hot oil and measure.
  • Read off the TPM value - job done.

Interpretation of the TPM value is particularly easy thanks to the background illumination of the display:

  • Green (less than 20% TPM): all OK
  • Orange (between 20 and 24%): the oil is still OK. However, you should think about replacing it.
  • Red (more than 24% TPM): the oil must be replaced

Robust, simple and convenient for the kitchen
With its reliable measuring technology, the testo 270 cooking oil tester is your competent partner when it comes to ensuring quality assurance for your deep fryer, whether you are using the instrument in your restaurant business, commercial kitchen, in catering, food inspection, or in the quality assurance or production of food.

The cooking oil tester is easy to use: you can set the required TPM limit values in advance, and protect them from being modified inadvertently with a PIN. The cooking oil tester’s display will assist you during the measurement itself: it will flash until a stable reading is reached. The display signalling function in traffic light colours (red, yellow and green) enables quick detection of the measurement result range. Naturally, the accurate reading in %TPM can also be read off on the display.

How long does cooking oil remain good?
That always depends on which oil you use and how often you fry. However, to be on the safe side, regular measurement with a cooking oil tester is recommended. The instrument enables a frying oil test to be carried out quickly and you can fry with a clear conscience. Depending on the utilization of the deep fat fryer, it may be advisable to measure the quality on a daily basis at first and then to extend the intervals.

Save cooking oil
Regular measurement with the testo 270 prevents the cooking oil from being replaced too early or too late – this can reduce your cooking oil consumption by up to 20%, thus saving costs.
