This Cooking Oil Tester is a portable measuring instrument designed to quickly detect the aging of frying oil. The TPM value (total polar component) reflects the deterioration of edible oil due to high temperature during frying process.The sensor uses the change in capacitance value to determine the total polar component content by unit of %. The following measurement tasks can be performed by the Cooking Oil Tester:

  • Display the temperature value of the frying oil: accurately indicate the actual oil temperature of frying oil, and correct the accuracy of self-contained thermometer of the frying pan.
  • Display TPM value: an indication of degree of deterioration of frying oil.

What kind of oil/grease can this instrument be used to detect? In principle, all oils and fats that are fried can be measured. Vegetable oils such as canola oil, soybean oil, sesame oil, palm oil, olive oil and peanut oil can also be measured.Depending on type of fat, the TPM of fresh oil will fluctuate between a few percent. The maximum use time of frying oil will vary.The acid value is used to evaluate the quality of unfried oil. This instrument is not used for the detection of acid value. The measured frying oil temperature is at least 10° C (the frying oil is liquid and not crystallized), and the maximum is 200° C.When the instrument measures common frying oil, the error is slightly larger when tested at 40° C (104 ° F) or less because of the different freezing points of various oils.The probe is 0.4″ (1 cm) from the measuring tip to probe handle or plastic shell. When it is operated, please follow the immersion depth specified in operating instructions or mark on the probe.Our measuring instruments are inspected before shipment to ensure the accuracy. In order to ensure the high measurement accuracy of instrument, we recommend that you regularly calibrate the instrument.


You have the following options:

  1. Return to Emerson for calibration.
  2. The user calibrates himself during frying process.

We recommend that you measure the unexpanded edible oil after it is heated to 50°C when first using a new instrument. It is best to perform multiple measurements in succession and repeat, and record the TPM value for each measurement. The average of these readings will be the reference for your future calibration. In the future, when calibrating the instrument, the unfried cooking oil is heated to 50°C and calibrated with the previously recorded calibration reference value.Please note that the reference values described will need to be re-recorded when replacing other types of cooking oil or changing the supplier of cooking oil.The following is used to record your calibration values:The type of measured oil is: ________________________The calibration reference value is: ____________________

Instrument Appearance And Working Principle

Instrument appearance

Working principle


Edible oil is an important source for energy and nutrition of human beings and an important raw material for processed foods. Fried foods are popular with consumers for their unique flavor. Edible oils used for frying undergo a series of physical and chemical changes during high-temperature frying, which produce substances that are harmful to health.

At present, the traditional detection methods for frying edible oil are mostly chemical methods. These methods must be operated by professionals in the laboratory, which is time-consuming and laborious. The use of chemical reagents may harm the health of the test personnel, and the chemical waste agent may pollute the environment.This instrument is a fast, safe and efficient quality detector for edible oil that quickly detects the content of polar compounds in edible oils. This product can be used in high oil temperature environment and is suitable for quality inspection of various fried edible oils.

Sample testPlease follow the points below to get the most accurate results in your measurements:

  1. Turn off the induction frying pan during the measurement because the electromagnetic field will affect the measurement results.
  2. Please clean the probe before each measurement or before the next continuous measurement. See the cleaning instructions of probe for details.
  3. Try to avoid touching the probe with metal objects. For example, frying baskets, pot walls, because these things may affect the measurement results, the minimum spacing from metal objects is at least 1cm.
  4. Uneven oil temperature in the frying oil may cause measurement errors. Please stir the instrument quickly in the frying oil.
  5. If the measurement result is suspected to be wrong because it contains water: Please repeat the measurement after 5 minutes (do not fry during this period to keep the grease high temperature). If the new reading goes low, measure again after 5 minutes until the reading is stable.
  6. Please replace the frying oil when it reaches 24% TPM. Different countries have different limit values. Please be sure to replace the frying oil before reaching the limit value.
  7. When the automatic hold function is turned on, immerse the probe in the frying oil, pay attention to the immersion depth! If the temperature is within the allowable measurement range (0° – 200° C / 32° to 392° F), wait until Auto Hold appears on the screen. After the reading is stable, taking the instrument out of the frying oil will automatically maintain the measured data, which will make it easy to observe and record the data.

Shutdown operation

  1. After each use of the instrument, press the power key to turn off the instrument.
  2. After waiting for the probe temperature to cool down (to around room temperature), wipe off the sensor surface and the grease on the probe by test paper. Insert the probe cover onto the sensor to protect the sensor from damage.
  3. Store the instrument in a box.
  4. Store it in a dry environment.

Analysis and Elimination of Failure

Serial No

Fault phenomenon Cause Analysis Method of exclusion



Press the power key, the screen does not appear on the screen 1. The lithium battery is low in power;

2. Instrument failure.

1. Use the instrument after charging it;

2. It cannot be turned on under charging status.


When using the computer to configure the instrument, there is no COM port. Poor connection of data lines;

The USB driver corresponding to the computer is not installed


Unplug the data cable and reconnect it;

Install the CP2102 driver of the corresponding system, download it yourself or contact our sales staff to request the driver.


Data in the air is abnormal, TPM is not 0 1. The sensor cover is not removed;

2. There are stains on the sensor surface.

1. Remove the sensor cover;

2. Wipe the sensor surface with a test strip.


The data is abnormal when the edible oil in low temperature is measured. When the temperature is too low, it will cause the edible oil to crystallize or be close to the crystalline state. After heating the edible oil to 50°C (122°F,) stop heat and re-measure it.


Wi-Fi connection is abnormal Wi-Fi parameters are not set correctly Configure the Wi-Fi parameters of instrument using the corresponding configuration software.

If not resolved, please call our technical staff to solve the problem.


Connection for Bluetooth printer is abnormal Parameters of Bluetooth printer are not set correctly;

Use it when the printer is not initialized.

1. Configure the parameters of Bluetooth printer by corresponding configuration software.

2. Turn on the Bluetooth printer first, wait 10 seconds, then turn on the instrument Bluetooth.

Calibration instrumentWe recommend unused edible oil for calibration. The instrument should be calibrated regularly with calibration oil. We recommend that you calibrate it every 3 months to ensure accuracy and quality.The calibration steps are as follows:

  1. Clean the probe before calibration, see the cleaning instructions section of the probe.
  2. Heat the calibration oil used for calibration in water, and stop heat after heating it to about 50°C (122°F).
  3. Calibrate the calibration oil in a room temperature environment.
  4. Immerse the probe in calibration oil, paying attention to the immersion depth.
  5. In order to get the reading faster, stir the probe in the oil, read the display data and record it after temperature is stable. The TPM adjustment value is calculated by comparing the previously recorded calibration values.

Modify the TPM value to be adjusted by the “TPM Adjustment Value” menu in the setup menu, then press [Hold] key (<1 second) to save and exit the menu.Turn off the instrument, the calibration is completed, and the instrument will take effect after restarting.
