Description
Change frying oil on time and reduce costs: with the testo 270, you can work more reliably, intuitively, and efficiently.
The fryer oil tester becomes your competent assistant in maintaining consistent quality during frying.
Simple monitoring of frying oil with the testo 270 ensures you do not exceed TPM limits and change the oil at exactly the right moment.
With the testo 270, you can perform measurements directly in hot oil across various fryers without any delay. The fryer oil tester offers numerous advantages, including a robust oil sensor, easy three-button operation, and more.
Durable, simple, and convenient kitchen instrument
Thanks to reliable measurement technology, the testo 270 is your trusted tool for controlling frying oil quality in restaurants, catering operations, food inspections, and food production.
The fryer oil tester is easy to use: you can preset the required TPM limit values and protect the settings with a PIN code. The blinking display, which continues until a stable value is reached, also helps during measurements. The graphical display works like a traffic light (red, orange, green), allowing you to quickly interpret measured values. The exact TPM percentage is also shown on the display.
Key advantages of the testo 270 fryer oil tester
- Ease of use: intuitive operation, three-color backlit display, and capacitive oil sensor allow multiple sequential measurements in boiling oil without pre-cooling the tester.
- Measurement accuracy: calibration is performed on-site using reference oil.
- Durability: fiberglass-reinforced housing makes the device shock-resistant. The oil sensor is in a metal casing for protection. The device is IP65 rated, so it can be washed under running water.
- Safety: the ergonomic design protects the user from hot oil exposure.
- Clear results: the TPM content is displayed as a percentage and accompanied by a traffic-light color backlight (red, orange, green); Hold and Auto-Hold functions allow values to be fixed on the display.
Applications of the testo 270
During frying, a series of chemical reactions occur in the oil, including oxidation, polymerization, and hydrolysis, which directly affect fat quality. The quality of the fried product depends on the oil used, making monitoring essential.
Fat molecules consist of glycerol and three fatty acids. During frying, the fatty acids separate from glycerol through chemical reactions, forming breakdown products such as aldehydes and ketones. These are measured as Total Polar Materials (TPM). The TPM percentage affects not only oil consistency, taste, and appearance but also its suitability for frying.
The testo 270 quickly and reliably determines oil quality by measuring TPM and presenting the result as a percentage. Old oil shows elevated TPM values. Using such oil results in lower-quality fried products and potential health hazards. Regular testing with the testo 270 prevents negative consequences and unnecessary premature oil changes, reducing oil consumption by up to 20%.
The testo 270’s ergonomic design ensures the handle is protected from hot oil. The three-color display system simplifies oil quality assessment: green indicates TPM within limits, yellow indicates TPM nearing the limit, and red indicates TPM exceeded. TPM limit values can be customized and protected with a PIN code.
