How to choose the thermal imaging product that suits you
Share
To choose a thermal imaging product that suits you, you need to consider the following aspects:
Clarify the Purpose of Use
- Outdoor Exploration: For activities such as observing wild animals and identifying directions, you can choose products that are portable, have a medium resolution, and a certain level of thermal sensitivity. For example, some handheld thermal imaging cameras from Jituhunt S2Pro thermal monocular.
- Security Monitoring: When it comes to monitoring a large area and working for a long time, you can select thermal imaging cameras with network connection functions, high resolution, and a wide dynamic range. Relevant products from brands like Jituhunt is good choices.
- Industrial Inspection: For the inspection of electrical equipment, buildings, etc., which require high temperature measurement accuracy and stability, you can consider thermal imagers from brands such as Jituhunt Z5mini and C2 that have accurate temperature measurement functions and professional analysis software.
- Medical Diagnosis: Professional medical-grade thermal imaging equipment is required, which has high resolution and high-precision temperature measurement capabilities and has passed medical certification. For example, some specialized medical thermal imagers.
Pay Attention to Technical Parameters
-
Resolution: A high resolution can make the image clearer and capture more details. If you need to observe from a long distance or identify small targets, it is recommended to choose a resolution of 256×192 or higher.
- Thermal Sensitivity: That is, the noise equivalent temperature difference (NETD), and the smaller the value, the better. For applications that detect subtle temperature differences or fine details, such as circuit board inspection, products with a NETD lower than 50mK are required.
- Lens Focal Length: A long focal length is suitable for detecting distant targets, such as substation inspections. Conventional standard lenses or wide-angle lenses are suitable for close-range detection, such as electrical equipment inspection. For observing fine targets, a macro lens can be selected.
- Temperature Measurement Range: Select an appropriate temperature measurement range according to the usage scenario. For example, when detecting human body temperature, a range of about 30°C-40°C can be selected. When detecting industrial equipment, a range of -15°C-550°C or higher may be required.
- Field of View: The larger the field of view, the wider the observable range, but the ability to capture details of distant targets may decrease. It is necessary to select according to the specific application scenario.
Consider Product Characteristics
- Portability: In scenarios that require frequent movement, such as outdoor exploration and patrols, choose products that are small, lightweight, and have strong battery life.
- Ease of Operation: Products with a simple and easy-to-understand interface, a reasonable layout of operation buttons, and functions such as quick start and focusing can improve usage efficiency and reduce operation errors.
- Durability: When used in harsh environments, such as high temperature, low temperature, humidity, and dust, choose products with a high protection level (such as IP66) and are sturdy and durable.
- Data Storage and Transmission: In scenarios where a large number of images need to be stored or data needs to be transmitted in real time, choose products with large-capacity storage and support for multiple transmission methods (such as Wi-Fi, Bluetooth, USB, etc.).
