Electrostatic Charge Attenuation Tester ToronPC™ ECAT is an advanced electrostatic charge attenuation tester designed for precise analysis. It features a high-performance step voltage generator, optimized signal acquisition, and computer-controlled real-time monitoring. Ideal for measuring half-life, shielding efficiency, and voltage-time curves with exceptional accuracy.
The sample was charged using a step voltage induction method. Its half-life and shielding efficiency were measured in a non-contact state.
