Decoding the Technology: Understanding Thermal Camera Specifications and Features
Let's talk about infrared thermography:
Infrared thermography is a diagnostic technology that speaks volumes through visuals. It allows instant visualization and verification of thermal performance, making it unique in its capabilities. Acision infrared cameras excel in revealing thermal issues and offer precise non-contact temperature measurements, providing invaluable quantification of the problems.
To share, Acision HTC7630 is a camera with both optical images and thermal images. The built-in high-sensitivity IR detector and high-performance sensor detects the temperature change and measures the real-time temperature.
Let's go in depth:
What are the 3 key features you need for a thermal camera?
- Resolution = Detector resolution indicates the number of detector pixels on the camera. More pixels mean more detail, and a greater likelihood of getting an accurate measurement. For the Acision HTC7630 model, it has a thermal resolution of: 384 x 288 (110,592 pixels) which is under a mid-range category, and a higher end model has an estimated 300,000 pixels. With a huge difference in the resolution, it is suitable for professional use.
- Focus Mechanism = With manual focus, it allows precise incremental focus adjustments for fine-tuning the image based on the user’s judgment. The Acision HTC7630 offers manual focus whichcan capture sharp images and more accurate results from further away.
Let’s dive into Manual focus, this feature in thermal cameras are primarily utilized by experienced thermographers due to their higher resolution capabilities. These cameras allow for precise focusing, making them ideal for close-up targets and capturing sharper images from greater distances.
- Thermal Sensitivity (NETD)= Thermal sensitivity, represented by Noise Equivalent Temperature Difference (NETD), indicates the minimum temperature difference discernible with a thermal device. A lower NETD value, measured in milliKelvin (mK), signifies a superior sensor capable of detecting small temperature variations more effectively. You can gauge the quality of a thermal detector using the scale provided below.
- <30 mK (Excellent)
- <40 mK (Great)
- <50 mK (Good)
- <60 mK (Acceptable)
- <80 mK (Satisfactory)
The Acision HTC6730 stands out from other options due to its excellent NETD level which is at < 35mK (@ 25 °C), which represents its superior thermal sensitivity and ability to detect even the smallest temperature differences. What makes this thermal camera even more appealing is that it offers these high-end features at an affordable price point compared to higher-end brands.
So, with the Acision HTC6730, you get exceptional performance and cutting-edge technology without breaking the bank.
