Cooking oil quality measurement

The electronic testo 265 oil tester is a compact, electronic handheld instrument that is suitable for daily use. The main part of the instrument is a sensor developed by Testo, which can be immersed directly in the hot cooking oil. After approximately 25 to 30 s, the instrument shows the number of polar components directly in the display. The current cooking oil temperature is shown in a second display line. Two limits, which trigger a light-emitting diode whose colours depend on the oil quality, can be set in the instrument making operation easy.

If this light-emitting diode is green, the cooking oil is fresh; a yellow display indicates that the oil is slightly used; a red display indicates that the oil should be changed soon. Both limit values (threshold values from green to yellow or yellow to red) can be defined by the user. In this way, anyone can measure cooking oil quality quickly and efficiently.

The testo 265 does not need to be adapted to the cooking oil used, therefore users can use any standard oils and fats. If the tester comes into contact with cooking oil it is easy to clean under running water if it comes into contact with cooking oil due to the ‘TopSafe’ protective case supplied. Since the TopSafe is resistant to heat, it can even be cleaned in the dishwasher.

The testo 265 can measure cooking oils in the range from +40 to +200 °C as a result of the built-in temperature compensation function. If this value is exceeded, it is shown clearly in the display. Due to the temperature display, it will no longer be necessary to have additional thermostat checks on the deep-frying bath using a separate electronic thermometer.
