NF522 vs NF521s vs NF586s vs NF521 Comparison

Features & Benefits

  • High Resolution: The camera has a high thermal imaging resolution of 120 * 90 pixels, providing clear and detailed thermal images. And 25Hz refresh rate ensures the video recording is smooth, not stilted and flickering.

  • Wide Temperature Range: The handheld thermal imager can measure temperatures between -4 °F to 752 °F (-20 °C to 400 °C), making it suitable for a wide range of applications, such as electrical inspection, mechanical inspection, building inspection, HVAC inspection, pet search, night vision, anti-candid photography, etc.?

  • Multiple Color Palettes: The thermal imaging camera offers 8 different color palettes to choose from, including iron red, white heat, black heat, rainbow, red heat, high contrast, green heat, and lava, to enhance the visibility of temperature differences.

  • Low NETD (Noise Equivalent Temperature Difference). The NF-521S boasts a thermal sensitivity or NETD of 65mK, which allows it to distinguish between minute temperature differences and generate more intricate thermal images.

  • Adjustable Emissivity: The emissivity of the camera can be adjusted between 0.1 and 0.99, allowing for accurate temperature measurements of various materials.

  • Non-Contact Measurement: The camera can measure temperature from a safe distance without making contact with the object or surface being measured, reducing the risk of contamination or damage.

  • Data Storage and Transfer: The camera has built-in memory for storing up to 500 images, and the images can be transferred to a computer for further analysis using the included USB cable.

Great product

One of the things I like best about this thermal camera is the SD card slot. It's so convenient to be able to save my images and videos to a memory card. Also, appreciate that the camera is rechargeable, so I can just plug it in when I'm done using it. The controls are very easy to use, and the image quality is excellent. I've been really happy with the way the camera has performed, and I would definitely recommend it to anyone looking for a thermal imaging camera.

Perfect Product

I was happy with the timely delivery, the reasonable price, and the user-friendly product.


It's fantastic! I absolutely love it! Suitable for noncontact examination of electrical control panels on industrial machinery.
