The alarm function tells you when
its time to change the oil

The LED alarm bar in the display
lights up either yellow or red when
your quality limit values are exceeded
(e.g. 18 % TPM for a lower alarm point
– yellow; 24% TPM for a higher alarm
point – red). Alarms are also triggered
if the frying temperature is too high.

Reduce your costs and ensure fried food quality

It may not look it at first glance, but frying is a complex and dynamic
process. Cooking oil, as it fries foods, breaks down because of
interactions between the oil, food, heat, and oxygen in the air.
By-products, or total polar materials (TPM) are produced, the most
common index of oil abuse

(1)

. TPM is the generic term for free fatty
acids (FFA), monoglycerides, diglycerides, and a number of oxidation
products (aldehydes or ketones) found in cooking oil as it breaks
down.

The model 270 measures all these by-products in %TPM, from 0 to
40% TPM. Many companies use 24% TPM as a maximum limit.
You can even measure the quality of your stored or make-up oil, or
to check when different oil blends are used.
