Ready for the Course: How to Buy the Right Thermal Imagers
Introduction
Thermal imagers, also known as infrared cameras, are invaluable tools for a variety of applications, including building inspections, electrical maintenance, and even search and rescue missions. Choosing the right thermal imager can make a big difference in the quality and accuracy of your work, so it's important to take the time to research and compare your options.
Key Factors to Consider
There are several key factors to consider when choosing a thermal imager, including its resolution, temperature range, and field of view.
Resolution
The resolution of a thermal imager refers to the number of pixels it has, which determines the level of detail it can capture. Higher resolution thermal imagers can produce clearer, more detailed images, but they are also more expensive. It's important to choose a thermal imager with a resolution that is appropriate for your needs.
Temperature Range
Another important factor to consider is the temperature range of the thermal imager. Different thermal imagers are capable of detecting different temperature ranges, so it's important to choose one that is suitable for your intended use. For example, if you need to detect very high or very low temperatures, you'll want to choose a thermal imager with a wide temperature range.
Field of View
The field of view of a thermal imager refers to the area it can detect at a given distance. A wider field of view allows you to see more of your target area at once, which can be useful in some situations. However, a narrower field of view can provide more detailed images, so it's important to consider which is more important for your needs.
Additional Features
In addition to the key factors mentioned above, there are several other features to consider when choosing a thermal imager.
Sensitivity
The sensitivity of a thermal imager refers to its ability to detect small temperature differences. A more sensitive thermal imager can pick up on subtle temperature changes, which can be useful in some situations. However, higher sensitivity also increases the price of the thermal imager, so it's important to weigh the benefits against the cost.
Image Storage and Transfer
If you need to save and share your thermal images, you'll want to choose a thermal imager with built-in storage and the ability to transfer images to a computer or other device. Some thermal imagers have built-in memory, while others require the use of an external memory card.
Display
The display of a thermal imager is important for previewing and reviewing your images. Most thermal imagers have a small, built-in display, but some also have the option to connect to an external display for a larger view.
Conclusion
Choosing the right thermal imager can make a big difference in the quality and accuracy of your work. By considering factors such as resolution, temperature range, and field of view, as well as additional features such as sensitivity, image storage and transfer, and display, you can find a thermal imager that is well-suited to your needs.
Frequently Asked Questions (FAQs)
1. What is a thermal imager used for?
Thermal imagers are used primarily to check the body temperature and surface temperature of animals, commonly performed on pets.
2. Are thermal imagers legal?
The use of thermal imagers typically requires a warrant, as determined by the 9th and 10th Federal circuits. This is because thermal imagers have the ability to see beyond walls, raising privacy concerns.
3. Can I use my phone as a thermal camera?
Yes, there are thermal imaging attachments available for smartphones, such as the Seek Compact, which can transform your phone into a thermal imaging tool. This allows you to take thermal photos and videos, share findings, and document your observations conveniently.
4. Can thermal imaging see through walls?
Thermal imaging devices cannot see through walls. However, they can detect and read the heat radiating off objects. This means that pointing a thermal camera at a building can still reveal information about the temperature distribution and potential anomalies inside.
5. What are 3 benefits of using thermal imaging?
Some benefits of using thermal imaging include the ability to collect data in hazardous environments from a safe distance, quickly scan large areas like walls and ceilings, and identify irregularities in specific locations. Thermal imaging also allows for the detection of problems before they lead to failure.
6. Can a civilian own a thermal scope?
Yes, in the United States, U.S. citizens and permanent residents are allowed to own and use night vision and thermal optics. However, it is illegal to take these devices out of the country without proper licensing from the U.S. State Department.
7. Can thermal imaging see through woods?
Thermal imaging devices typically cannot see through woods or trees due to the heat-isolating properties of wood. The thermal radiation is hindered, making it difficult for the thermal imager to detect objects through the wood.
8. What app turns your phone into a thermal camera?
There are several apps available that can turn your phone into a thermal camera, such as Thermal Camera HD Effect, Thermal Camera VR, InfraredCamera Free, and Night Vision Thermal Camera AR: Scope & Biocular. These apps utilize the capabilities of your phone's camera to simulate thermal imaging.
9. Is thermal imaging better than infrared?
Thermal imaging cameras are more advanced compared to infrared thermometers as they can accurately detect temperatures over greater distances. The advanced optics of thermal imaging cameras allow for more precise temperature measurements.
10. What are the cons of thermal imaging cameras?
Some drawbacks of thermal imaging cameras include the high initial investment cost, difficulty interpreting images in objects with erratic temperatures, and challenges in obtaining accurate temperature measurements due to differing emissivities and surface reflections.
