What is the temperature range and accuracy?

It measures from -40°C to 300°C. Accuracy is ±2°C in the central area between 0 and 100°C; expect wider error outside that band.

How fast does the screen update?

The refresh rate is 8Hz, so the image updates about eight times a second. Slow scans of walls and panels are fine; fast-moving targets will smear.

How long does the battery last and how does it charge?

The built-in 750mAh battery gives roughly 4 hours of use and charges in about 1.5 hours through a Micro-USB 5V 1A port.

Can I change how temperatures are colored?

Yes. It offers iron red and colorful palettes, and you can adjust emissivity from 0.1 to 0.99 for different surfaces.

What comes in the box?

The thermal imager, a USB cable and a portable rope. The battery is built in and shipped with the unit.

Is it good for finding drafts and insulation gaps?

Yes for slow indoor scans. The wide 75x110° field of view covers a lot of wall at once, but the 8Hz refresh and ±2°C accuracy limit fine diagnosis.

Our take on the 2.4in LCD Display Infrared Thermal Imager

This is a pocket-sized thermal camera with a 2.4-inch LCD, a 320x240 sensor and a -40°C to 300°C range. It reads ±2°C accuracy in the central area between 0 and 100°C, shows center, max and min temperatures, and switches between iron-red and colorful palettes. The 8Hz refresh rate and 75x110° field of view are modest next to higher-refresh handhelds, but the built-in 750mAh battery runs about 4 hours and charges over Micro-USB. It suits homeowners and hobbyists checking insulation, wiring, pipes and electronics, not users who need fast motion capture or certified calibration.
