1. Introduction
The Testo 270 Cooking Oil Tester (Model 0563 2752) is a precision instrument designed for quick, efficient, and safe determination of the temperature and quality of cooking and frying oil. This device helps ensure that frying oil maintains proper quality, preventing compromised taste and nutritional value of fried foods, and avoiding premature disposal of expensive oil. By regularly measuring temperature and Total Polar Material (TPM), the Testo 270 supports food quality, employee safety, and cost savings in both professional and private settings.
This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your Testo 270 Cooking Oil Tester. Please read it thoroughly before initial use and keep it for future reference.
2. Consignes de sécurité

- Exercise extreme caution when measuring hot oil. The oil can cause severe burns. Use the ergonomic grip to protect your hand.
- Ensure the oil temperature is within the specified operating range before measurement.
- N'utilisez pas l'appareil s'il semble endommagé.
- Gardez l’appareil hors de portée des enfants.
- Only use the device for its intended purpose as a cooking oil tester.

4. Mode d'emploi
4.1 Mise sous/hors tension
Press the power button (usually marked with a circle and vertical line) to turn the device on. Press and hold the same button to turn it off.
4.2 Prendre une mesure
- Ensure the oil is at the appropriate temperature for measurement (typically between 104°F and 374°F / 40°C and 190°C).
- Carefully immerse the probe into the hot oil. Ensure the immersion depth is sufficient (approximately 1.38 inches / 35 mm) to cover the sensor.
- Hold the device steady. The display will show the temperature and Total Polar Material (TPM) percentage simultanément.
- The device features a traffic light system for TPM levels:
- Vert: Oil quality is good (TPM below threshold, typically < 20%).
- Orange: Oil quality is borderline (TPM approaching threshold, typically 20-24%).
- Rouge: Oil quality is poor, oil needs changing (TPM above threshold, typically > 24%).
- Use the "HOLD" function to freeze the displayed measurement for easier reading.
- Remove the probe from the oil after measurement.
