1. ভূমিকা
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. নিরাপত্তা তথ্য
যন্ত্রের আঘাত এবং ক্ষতি রোধ করতে সর্বদা নিম্নলিখিত নিরাপত্তা সতর্কতাগুলি অনুসরণ করুন:
- 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.
- ডিভাইসটি ক্ষতিগ্রস্ত হলে ব্যবহার করবেন না।
- ডিভাইসটিকে বাচ্চাদের নাগালের বাইরে রাখুন।
- Only use the device for its intended purpose as a cooking oil tester.

4.1 পাওয়ারিং অন/অফ
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.
৩.১ একটি পরিমাপ গ্রহণ করা
- 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 একই সাথে।
- The device features a traffic light system for TPM levels:
- সবুজ: Oil quality is good (TPM below threshold, typically < 20%).
- কমলা: Oil quality is borderline (TPM approaching threshold, typically 20-24%).
- লাল: 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.
