The testo 270 cooking oil tester measures Total Polar Material (TPM) content in the oil and displays this as a percentage.

As the oil is used, TPM increases. For every deep fried food, there is a point where overused oil will compromise the cooking oil quality and taste and presentation of that food. Measuring the %TPM level assures that the quality of the oil is optimized without fear of endangering the brand. In addition to this, a % TPM reading of greater than 24 can cause health concerns. Regular measurement with the testo 270 can prevent this. The use of the cooking oil tester also prevents changing the oil too soon, thus tossing away a very expensive commodity before you should have. The TPM limit values can also be individually defined, and can, like other instrument configurations, be protected from inadvertent configuration changes by a PIN.
