Application:

Designed for use by China Solar Cell Tester Factories, this advanced IV Tester is ideal for testing the electrical performance of Mono-Si or Poly-Si solar cell pieces. Acting as a reliable Desktop IV Tester, it records test results and data files to support efficient quality control across modern production lines. This piece of IV Testing Equipment is a trusted choice for manufacturers seeking precision and consistency.

Machine Feature:

• Provides an A-grade spectrum and an A-grade degree of uneven irradiance for superior accuracy.
• Equipped with a four-line measure and a 14-bit 4-channel high-speed synchronous acquisition card to support rapid testing as part of an IV Tester system.
• Displays 10 parameters in both tabular and graphical formats, making it a versatile Desktop IV Tester in any production environment.
• Incorporates pneumatic and buffering contact along with automatic temperature compensation to ensure stable performance.
• Features voice counting and flash count prompts for continuous operation, enabling 24-hour work cycles without interruption.
• Ideal for integration into larger systems developed by leading China Solar Cell Tester Factories.
