Measuring thermal energy of surface contaminants

In summary, the conversation discusses the use of a heat source to detect temperature differences in agricultural commodities such as corn. The use of a thermal camera, specifically the FLIR SC7000 Series, is suggested as a means to detect surface contaminants like mold or fungus. The camera's high sensitivity of up to 20 mK is capable of distinguishing between clean and contaminated corn kernels. The suggestion is made to contact the manufacturer for further information.

Using a heat source to increase the temperature of an agricultural commodity like corn, could a thermal camera detect temperature differentials over time as the commodity cools, versus localized surface contaminants such as mold or fungus? I'm thinking yes in theory but the differences might be imperceptibly small and thus undetectable by a thermal camera (such as flir for example).

The FLIR SC7000 Series specification says:

“High Sensitivity: up to 20 mK
20 mk thermal sensitivity captures the finest image details and temperature difference information.”

So, it would seem that it could easily discriminate a “clean” kernel of corn, for instance, from one covered with mold or fungus.
I suggest you contact the manufacturer with your question.
 

1. What is the purpose of measuring thermal energy of surface contaminants?

The purpose of measuring thermal energy of surface contaminants is to determine the amount of heat energy that is present on the surface of an object. This can help to identify any potential hazards or risks associated with the surface contaminants, and can also aid in determining the most effective method for removing or controlling them.

2. How is thermal energy of surface contaminants measured?

Thermal energy of surface contaminants can be measured using various methods, such as infrared thermography, contact thermometers, or thermal imaging cameras. These methods involve measuring the temperature of the surface and calculating the amount of heat energy present.

3. What factors can affect the accuracy of thermal energy measurements?

The accuracy of thermal energy measurements can be affected by factors such as the type of surface contaminant, the material and thickness of the surface being measured, and environmental conditions such as humidity and air flow. It is important to consider these factors when interpreting thermal energy measurements.

4. Why is it important to measure thermal energy of surface contaminants?

Measuring thermal energy of surface contaminants is important for several reasons. It can help to identify potential safety hazards, determine the effectiveness of cleaning or decontamination methods, and assess the overall cleanliness and quality of a surface. It can also aid in preventing the spread of contaminants and maintaining a safe and healthy environment.

5. Are there any safety precautions that should be taken when measuring thermal energy of surface contaminants?

Yes, it is important to take safety precautions when measuring thermal energy of surface contaminants. This may include wearing appropriate protective equipment, following proper measurement techniques, and ensuring that the measuring equipment is calibrated and functioning correctly. It is also important to be aware of potential hazards associated with the surface contaminants being measured.
