Things To Consider When Buying The Best Thermal Imaging Camera

Certainly, here are the top things to consider in detail before buying a thermal imaging camera:

1. Resolution

The typical resolutions available are 160 x 120, 320 x 240, and 640 x 480 pixels. For instance, a 160 x 120 resolution yields 19,200 pixels, whereas a 640 x 480 resolution offers a much higher 307,200 pixels. Opting for a higher pixel density results in sharper and more intricate images.

2. Thermal Sensitivity

Thermal sensitivity is the minimum temperature change detectable by a thermal imaging camera. If a thermal imager has a thermal sensitivity of 0.05°, it can distinguish between two surfaces with a temperature difference as small as 0.05° by representing the cooler and warmer areas with distinct colour variations. Additionally, ensure that the thermal imager has an adequately wide temperature range to avoid any limitations. A typical example of a suitable thermal range is -4°F to 2,192°F.

3. Thermal Range

Determine the working distance or thermal range you need. Some cameras are designed for close-up inspections, while others are suitable for longer-range measurements. Choose a camera that matches your specific requirements.

4. Frame Rate

For applications involving fast-moving objects or dynamic processes, the camera’s frame rate is crucial. Higher frame rates ensure that you can capture and analyze rapid temperature changes.

5. Portability and Size

Take into account the size and weight of the camera, especially if you need to carry it around for fieldwork. Handheld cameras are more portable and suitable for on-the-go use, while larger, stationary models may offer greater functionality but may be less convenient for mobility.

6. Battery Life

Assess the camera’s battery life, particularly if you plan to use it for extended periods without easy access to recharging. Longer battery life is essential for continuous operation.

7. User Interface and Ease of Use

A user-friendly interface is crucial, especially if you’re not an experienced thermal imaging professional. A well-designed interface simplifies camera operation and makes it easier to interpret the collected data.

8. Data Storage and Transfer

Investigate how the camera stores and transfers data. Look for options such as removable memory cards or wireless data transfer to ensure convenient data management. The ability to quickly and efficiently transfer and store data is essential for efficient analysis and reporting.
