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. Safety Information
Always observe the following safety precautions to prevent injury and damage to the instrument:
- Do not immerse the entire device in liquid. The probe is designed for immersion, and the device is IP65 rated for cleaning under running water, but the main body should not be submerged.
- 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.
- Do not use the device if it appears damaged.
- Keep the device out of reach of children.
- Only use the device for its intended purpose as a cooking oil tester.

3. Setup and Initial Operation
3.1 Unpacking and Contents Check
Upon receiving your Testo 270, carefully unpack all components and verify that the following items are included:
- Testo 270 Cooking Oil Tester
- Carrying Case
- Short Instructions
- Full Instruction Manual (this document)
- Training Card
- Certificate of Conformity
- Batteries
3.2 Battery Installation
The Testo 270 operates on batteries. Locate the battery compartment, typically on the rear of the device, and insert the provided batteries, ensuring correct polarity. Close the compartment securely.
3.3 First Use and Calibration

4. Operating Instructions
4.1 Powering On/Off
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 Taking a Measurement
- 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 simultaneously.
- The device features a traffic light system for TPM levels:
- Green: Oil quality is good (TPM below threshold, typically < 20%).
- Orange: Oil quality is borderline (TPM approaching threshold, typically 20-24%).
- Red: 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.

5. Maintenance and Care
5.1 Cleaning the Device
The Testo 270 probe and shaft are designed for easy cleaning. The device has an IP65 protection rating, meaning it is protected against dust and low-pressure water jets from any direction. This allows for cleaning under running water.
- After each use, allow the probe to cool slightly.
- Wipe the probe shaft and tip with a soft cloth or paper towel to remove excess oil.
- For thorough cleaning, rinse the probe under running water. Ensure water does not enter the main housing of the device.
- Use a mild detergent if necessary, then rinse thoroughly with clean water.
- Dry the device completely before storage.
