Overview
The Feasa Functional LED Analyser is a multichannel tool that tests color and intensity across multiple LEDs in a single test cycle. Fast and reliable, it's trusted by production teams worldwide across automotive, medical, consumer electronics and telecoms, helping manufacturers achieve consistent product quality.
Manufacturing LED products at scale brings inherent variability — BIN ranking uncertainty, process effects like soldering, and natural light and color drift. The Functional Analyser addresses this directly, connecting via USB or RS232 with daisy chaining of up to 30 units, and shipping with a full software suite and DLL/SDK for test station integration.
It provides accurate, traceable and repeatable measurements that ensure every LED on your production line meets specification — a proven, cost-effective solution trusted across automotive and electronics production lines worldwide.s
Built for production. Trusted globally.
