LED Analyser

Streamline your ICT and Functional testing with Precitronic’s integrated Feasa and LEDProbe solutions. We offer precision color measurement and automated light shielding without the need for manual external protection.

Precision LED Analysis with Patented Light Shielding Technology

Precitronic SARL is the official integration, resale, and support partner for Feasa and Equip-Test across Morocco and the African continent. We deliver high-precision, automated measurement solutions for LEDs and LCD displays, tailored for the demanding medical, automotive, and aerospace sectors.

Feasa Analyzers provide fast, user-friendly testing of color, intensity, hue, and saturation. Their flexible design allows for seamless integration into most ATE (Automated Test Equipment) systems.

  • Feasa I – Optimized for ICT (In-Circuit Testing) applications.
  • Feasa F – Dedicated to FCT (Functional Testing) applications.

We offer full integration of these modules directly into your ICT/FCT test fixtures or as standalone system-side solutions.

The LEDProbe Advantage: No "Black Box" Required

To maximize ROI and testing accuracy, we integrate Equip-Test’s patented LEDProbe technology. This innovation solves the most common challenge in LED testing: interference from factory ambient light.

  • Patented Shielding: Spring-loaded LEDProbes perfectly seal the LED, blocking all external light.
  • Undistorted Transfer: Ensures rapid, mistake-free light transfer directly to the analyzer.
  • Simplified Fixture Design: Because the probes shield the light at the source, there is no need for bulky "Black Box" designs or manual internal shielding.

Customized Test Fixtures with Feasa

We design and manufacture fully customized Functional, ICT, and Dual-Stage fixtures. By combining Feasa’s analytical power with Equip-Test’s shielding, we provide a streamlined, "easy-to-integrate" solution that ensures high-accuracy results on even the busiest shop floors.
