Cooking Oil Tester

Testo 270 Cooking Oil Tester has the following features:

  • Capacitive oil sensor from Testo, together with its needs-based design. Making it possible to take measurements in hot oil (user is protected from the heat of the deep fat fryer)
  • IP 65: protected against water jets without a protective cover
  • Clear, visual alarm indication via highly-visible alarm backlight in traffic light colours
  • Washable case for hygienically stowing away at the application site

A visual or odour check is not sufficient to verify whether the quality of the cooking oil is still good. Chain restaurateurs with the Testo 270 cooking oil sensor only need to change the cooking oil once critical TPM values are reached. This saves them from changing the cooking oil more frequently than is necessary, enabling them to also benefit from the associated cost savings.

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 fat 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. At the same time, 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 helps you during the measurement itself: it flashes until a stable reading is reached. The display signaling function in traffic light colours (red, yellow, and green) enables quick identification of the measurement result range. Naturally, the accurate reading in %TPM can also be read off on the display.

  • Accurate: calibration possible at the measuring location using the reference oil
  • Robust: the fiberglass housing is extremely impact-resistant. Moreover, the oil sensor is embedded in a metal casing and is therefore unbreakable. In accordance with protection class IP65, it is protected against water jets and can be washed under running water
  • Reliable: users have protected from the heat of the cooking oil thanks to the measuring instrument’s ergonomic design
  • Clear: %TPM is shown on the large display, along with unambiguous signaling function of the display illumination in traffic light colours (red, yellow, and green); Hold and Auto-Hold function for the reading display
