What Is The Best Thermal Imaging Camera On The UK Market?

Thermal imaging devices can be unfamiliar to many people since they are mainly used by militaries or resourceful spies in movies. But latest advancements have paved the way for this technology to reach average consumers over the last decade. Though they are not exactly cheap, commercial thermal imaging cameras are increasingly becoming a standard unit for job site and home inspection, and would be seen in the toolbox of electrical or plumbing professionals, as well as thorough homeowners.

Just like any other devices, there is a variety of manufacturers with different models and versions. These devices can vary a lot in terms of resolution, temperature range, sensitivity, and more. To help you narrow down your list and make an informed decision, we’ve done a lot of research and testing to compile this list of top 5 best thermal imaging cameras. Keep reading to choose the right option for your needs.

Why Would You Need To Buy A Thermal Imaging Camera?

Thermal imaging cameras were initially created for the military during the Korean War. A few decades later, these devices have been adapted to meet a variety of other professional and commercial uses. In most cases, people use them to measure temperatures of solid objects or behind the walls; or check breaker boxes to ensure circuits aren’t overloaded. Also, they can be used for detecting HVAC leaks, water leaks, and missing insulation.

From a commercial perspective, thermal imaging cameras are often used to examine the operating temperatures of electronics and machines to find out possible malfunctions or issues. Detecting major temperature spikes as well as seeing through the walls can be helpful for homeowners to save a lot of money and effort in repairs. That’s why these units can be used by many people, such as auto mechanics, contractors, electricians, inspectors, and homeowners.

What To Look For When Buying A Thermal Imaging Camera?

Are you trying to figure out which thermal imaging camera is suitable for you? Here are some important features that you need to consider when choosing:

1) Resolution

This is perhaps the most important feature that determines the quality of a thermal imaging camera. Basically, models with higher resolutions will allow for more precise measurements and better image quality, especially with small details. Keep in mind that resolution and display are totally different. Perhaps the display of a camera has more pixels than the detector, but its actual image detail will be limited by the detector resolution.

2) Temperature range

For simple applications and home use, a temperature range from -10°C to 150°C is basically enough to spot HVAC problems, possible water leaks, or unsealed windows. If you are looking for a thermal imaging camera to use in professional inspections or factories, then you might need a higher range, at least from -40°C to 300°C, to examine any heat spot on active equipment which often operates at high temperatures.

3) Analytical software

Professional-grade thermal imaging cameras often come with advanced analytical software which can provide you with accurate measurements when connected to a computer. This feature will be especially helpful for professional use in a variety of industries. It helps you collect essential heat analysis data for further reporting. However, it would make a device cost more, so make sure to consider your needs before deciding to choose models.

4) Repeatability and accuracy

In most cases, a thermal imaging camera is not only used to detect but also to measure the differences in the temperature. Therefore, it is important to choose a model which can provide the most accurate readings repeatedly. Most high-quality units on the market often come with a 2% accuracy, more or less.
