The temperature measurement range of -40°C to 300°C is wide enough for most non-specialized applications. Accuracy is rated at ±2°C which is pretty standard. The 8Hz refresh rate provides real-time thermal imaging. The built-in storage can save 100 images for later analysis. Overall the features and performance are very good considering the affordable price point.

Technical Parameter Analysis


The resolution of a thermal imager refers to the minimum temperature difference its images can display. A higher resolution enables the clear visualization of subtle temperature changes in images, which is particularly important for some fine applications. The 320x240 pixel resolution of the Dilwe Thermal Imager Infrared Camera falls into the mid-range for its price segment, meeting the needs of most household and light industrial applications.


The sensitivity of a thermal imager refers to the smallest temperature difference it can detect. For applications requiring high-precision temperature measurements, such as medical diagnosis or industrial testing, higher sensitivity is crucial. The Dilwe Thermal Imager Infrared Camera performs well in sensitivity, accurately capturing subtle temperature changes, making it effective in various scenarios.

Temperature Range

The temperature range of a product determines the breadth of its applicable scenarios. The -40°C to 300°C temperature range of the Dilwe Thermal Imager Infrared Camera can meet the needs of most non-specialized applications, including home repairs, building inspections, and automotive diagnostics.

Battery Life

The 600 mAh lithium-ion battery lasts for about 4 hours of continuous use. This is decent but you may need supplemental batteries for extended use. Charging is via USB-C and takes around 4 hours. The camera can be used while charging which helps offset the shorter battery life.

Ease of Use

Operation is straightforward with just a few buttons to navigate the menu and capture images. The user manual provides clear instructions. Adjusting emissivity for different materials can be done right on the camera. The lack of wireless connectivity means you need to remove the SD card and use a card reader to transfer images.
