The WT3320 is the highest-resolution model in Muya's thermal imaging camera line, delivering a sharper 320x240 infrared image and a wider field of view than the WT3160/WT3220, making it easier to scan larger equipment or panels in one shot. It reads surface temperature from -20C to 300C, displays results on a 2.8-inch color screen with adjustable emissivity and multiple color palettes, and runs on a rechargeable battery good for a couple hours of continuous inspection work.
