3.1 Product Overview

Edible oil is a crucial source of energy and nutrition for humans and an important raw material in processed food. Fried food is popular among consumers due to its unique flavor. However, edible oil used for frying undergoes a series of physical and chemical changes at high temperatures, generating substances harmful to human health. Traditional detection methods for frying oil are mostly chemical, which require professional operation in laboratories, are time - consuming and labor - intensive. The use of chemical reagents may harm the health of detectors, and chemical waste pollutes the environment. The HM - SYP edible oil quality detector is a fast, safe, and efficient device that can quickly detect the content of total polar components (TPM) in edible oil. It can be used in environments with high oil temperatures and is suitable for quality inspection of various frying edible oils. In accordance with the "GB7102.1 - 2003 Hygienic Standards for Edible Vegetable Oils in the Frying Process", the TPM content of frying oil shall not exceed 27%, and this detector can effectively monitor this indicator.

3.2 Model Information

The only model of this product series is HM - SYP, which is an industrial - grade edible oil quality detector with comprehensive functions and wide application scenarios.

3.3 Detection Objects

• Sample Type: Various edible oils used for frying, including rapeseed oil, soybean oil, sesame oil, palm oil, olive oil, peanut oil, etc.

• Detection Indicator: Total polar component (TPM) content in edible oil, which reflects the deterioration degree of edible oil during high - temperature frying.

4. Core Technologies and Functional Features

4.1 Core Detection Principles

The TPM sensor of the HM - SYP edible oil quality detector adopts the capacitance sensor principle. Frying oil is a mixture of different polar substances. As the frying oil ages, the number of highly polar components increases. The detector determines the TPM content (expressed as a percentage) by measuring the capacitance change of the oil sample, thereby evaluating the deterioration degree of the frying oil. The temperature sensor uses a PTC sensor to accurately measure the temperature of the frying oil, and the instrument can correct the temperature to ensure the accuracy of TPM detection.

4.2 Functional Features

1. Convenient Operation: It supports on - site inspection and can be used in various operating environments without the need for professional laboratory conditions.

2. Rapid Measurement: It can obtain measurement results within 3 seconds, and has high - and low - frequency flashing prompts for different TPM content ranges to quickly identify oil quality.

3. No Secondary Pollution: The probe is made of food - grade 316 stainless steel, and other materials are also food - grade environmentally friendly materials, which will not cause secondary pollution to the detected oil.

4. Waterproof Design: The instrument has an IP67 protection level, which can resist the invasion of water and dust, and is suitable for humid or oily working environments.

5. Good Portability: It is equipped with a 900mAh lithium - ion rechargeable battery, which is economical, environmentally friendly, and durable. It uses a TYPE - C charging port for fast and convenient charging, and can be used continuously for no less than 30 hours. The instrument adopts a streamlined design that conforms to ergonomics, making it easy to hold. The probe has a spindle - shaped streamlined design, which reduces liquid retention and hanging after the test and facilitates wiping and cleaning.

6. Flexible Alarm Settings: Users can adjust the upper and lower limits of TPM alarm according to actual needs. When the TPM value exceeds the set upper limit or is lower than the set lower limit, the instrument will give a corresponding prompt.

7. Calibration Function: It has the function of calibrating the TPM parameters of the instrument, which can ensure the long - term accuracy of the instrument. Users can choose to return the instrument to the company for calibration (the company will calibrate at 3 points: 0%, approximately 5%, and approximately 27% TPM points in a precision laboratory in accordance with enterprise standards) or calibrate it by themselves in frying oil (heat the unused frying oil to 50℃, conduct multiple consecutive measurements, record the TPM value, take the average as the calibration reference value, and use this value for calibration when calibrating later; when changing the oil type or supplier, the reference value needs to be re - recorded).

8. Multiple Data Transmission Modes: The instrument can be connected to WiFi for wireless data upload, and can also upload data to a local upper computer. It is equipped with a cloud management platform as standard, which can manage, analyze, and evaluate historical data, and can also upload data to a third - party platform.

9. Data Storage and Management: It can effectively store up to 10,000 pieces of detection data. Users can read historical data, clear historical data, and export data to Excel files through supporting software.

10. Factory Reset Function: It supports restoring the instrument to factory settings, which is convenient for troubleshooting or reconfiguring the instrument.

11. Data Hold Function: It has the function of holding test data, which can lock the measured data to prevent data loss and facilitate observation and recording.

12. Adjustable Display Brightness: The OLED high - brightness LCD screen has 5 levels of brightness adjustable, which can adapt to different light environments and facilitate reading.
