Testo s 270 allows you to determine within seconds whether cooking oil needs changing. To do so, it measures the Total Polar Material (TPM) content in the oil, which is a sure indicator of its quality. It will then provide you with a reading and based on the colour of the screen display you will know the current state of the oil. Depending on the screen colour you will know if the oil needs changing or not. Green means the oil is perfectly fine, amber is when it s on the brink, and red means the oil needs changing immediately.

Benefits:

• Intuitive alarm notification via illuminated colour display based on the traffic light principle
• Ergonomic design for safe handling (sufficient distance from the hot oil)
• Washable under running water
• Certified according to HACCP International and NSF

There are a number of risks associated with using cooking oil that is past its best. As the oil begins to get older, the fried food becomes darker and could feature spotty surfaces.

In addition, the fried shell is less crisp and the food absorbs much more oil than usual. This can leave a bitter, unpleasant taste and is also unhealthy because of a higher content of saturated fats.

As the cooking oil continues to deteriorate the fried product will start to become hard, oily and the food inside might not even cook properly.

This can then cause problems from a food safety point of view. It can also produce a burnt flavour and give off a pungent smell. Essentially, the more times cooking oil is used and the longer it's left, the poorer the quality it will be and the lower the standard of the fried product.

The Testo 270 won the 2015 Product Excellence Awards.
