 Key Feature Differences

 The top key difference between these two thermal cameras is the infrared detector resolution - Fotric 326 thermal camera has 384x288 resolution compared to 320x240 resolution on the Flir E75 (44% more pixels on Fotric 326, or 33,792 more pixels). It means the Fotric 326 will provide higher quality and larger radiometric images, and can reveal more details. 

 The second key difference between Fotric 326 and Fluke TiS75 thermal camera is sensitivity (NETD). Flir E75 thermal camera has better thermal sensitivity and can detect a smaller temperature difference. 

 The third key difference between Fotric 326 and Fluke TiS75 thermal camera is the support of the smartphone. Fotric 326 thermal camera supports smartphone as the operational screen display and data processing with a smartphone APP, Fotric LinkIR. While Flir E75 thermal camera supports connection with a smartphone via WiFi to stream the image. You can always upgrade the smartphone to upgrade the overall Fotric 326 thermal camera performance while nothing you can do to the Flir E75 thermal camera.
