Presentation

Features

◆ 320×240 cooling type

◆ Built-in a variety of optional pseudo-color labels 

◆  Accurate temperature measurement: the highest temperature cross positioning, support multiple movable areas (the highest temperature, the lowest temperature capture, average temperature measurement), support multiple movable point temperature measurement

◆ Temperature measurement range: 0~ 350℃ ( range A 0~ 120℃,  range B1 100~ 180℃,  range B2 150~ 350℃)

◆ Temperature measurement accuracy: ±2 degrees or ±2% (reading range), whichever is the largest

◆ Support 1 channel alarm output

◆ Raw thermal image data output: the back-end manually collects a single frame of raw data images, and the collected data images can be analyzed and measured
