Two measurements. One device. Zero compromises.
- The LTDCM-4035 is the first color analyzer that can test two screen areas simultaneously. Built specifically for modern displays - from foldable phones to under-display cameras.
- Why it matters: Instead of testing one spot at a time, you get dual measurements instantly. That means faster quality control, better accuracy, and less time spent moving equipment around.
- Perfect for: Smartphone testing, foldable displays, automotive screens, and any next-gen display technology that demands precision.
