10 Best Cheap Thermal Imaging Camera 2025 in the United States

The HSFTOOLS HF96 Thermal Camera is an affordable option that offers notable features for thermal imaging. It boasts a 96x96 IR resolution, which can be enhanced to 240x240 using live super resolution technology, providing clear thermal images. The device has a temperature range from -4°F to 1022°F and a thermal sensitivity of less than 50mk, making it suitable for detecting small temperature differences. Its 25Hz frame rate ensures smooth imaging during inspections, and the 50° field of view allows for wide area coverage. The built-in laser pointer and seven color palettes enhance usability in various inspection scenarios.

The camera offers up to 8 hours of battery life and can store around 30,000 thermal images, which is convenient for prolonged use. It is also durable, featuring an IP54 protection rating and surviving drops from 6.6 feet, making it suitable for harsh environments. Additionally, the USB Cast Screen function allows for live sharing of the screen to a computer, aiding detailed inspections.

However, the image resolution, even with enhancement, may not match more expensive models, and the device's size might be cumbersome for prolonged handheld use. This thermal camera is a solid choice for users needing an affordable, durable, and reasonably accurate thermal imaging solution, especially for industrial or scientific applications.

The FLIR TG165-X Thermal Imaging Camera stands out as a solid option in the cheap thermal imaging camera category, especially for those needing a reliable tool for building inspections, HVAC, and electrical work. One of its main strengths is its impressive resolution of 48,000 pixels, which allows for clear thermal images. This is further enhanced by FLIR's patented MSX technology that combines visual and thermal images, making it easier to interpret data. The temperature range is quite broad, spanning from -25°C to 300°C (-13°F to 572°F), catering to various inspection needs.

The camera also features a built-in laser pointer, which helps users quickly identify measurement areas. Its rugged design is a plus for professionals working on-site, offering an IP54 rating that protects it from dirt and moisture. Battery life is commendable, supported by a rechargeable lithium-ion battery, ensuring you can work without frequent interruptions. Additionally, the lengthy warranty, including 10 years on the detector, showcases the manufacturer's confidence in its durability.

While it provides good thermal sensitivity, the NETD (Noise Equivalent Temperature Difference) isn’t specified, which could be an important factor for some users looking for precise readings. The display, although functional, is basic, and those seeking higher-end features, like Wi-Fi connectivity for image sharing, might find it lacking. Additionally, while the camera is lightweight, it may not have the advanced features found in pricier models, which could limit its appeal for more experienced users. The FLIR TG165-X is a user-friendly and effective thermal imaging camera for budget-conscious buyers looking for essential features for inspections and maintenance, but it might not meet the needs of users requiring advanced capabilities.

The FLIR C5 Compact Thermal Imaging Camera is a budget-friendly device offering solid performance for various inspection tasks such as electrical, mechanical, building, and HVAC applications. The camera boasts a high-temperature range, capable of measuring from -20 to 400°C (-4 to 752°F), which makes it versatile for different environments. One of its notable strengths is the 160 x 120 true thermal imaging resolution, providing 19,200 pixels for detailed imaging, supported by the patented MSX technology that enhances image clarity by embossing visual details over the thermal images. This feature is particularly beneficial for identifying and troubleshooting hidden faults quickly, thus saving time during diagnostics.

The FLIR C5 also offers excellent connectivity and documentation features, allowing users to directly upload images to the FLIR Ignite cloud, which is useful for creating professional reports and sharing them via email, enhancing work efficiency. The camera is compact and lightweight, weighing only 6.7 ounces, and includes a waterproof design, making it durable for fieldwork.
