Plus EIS Corrosion Package에 제공되는 PalmSens4는 USB 전원 또는 배터리로 구동되는 Potentiostat/Galvanostat/Electrochemical Impedance Spectroscopy (EIS) 분석기입니다.
PalmSens4는 높은 resolution과 낮은 noise로 큰 전압 범위(±5 V 또는 ±10 V)와 전류 범위(100 pA ~ 10 mA)를 가지고 있습니다.
기본 내장 배터리가 포함되어 있어 별도의 외부 전원 공급없이 사용 가능하며 블루투스가 내장되어 있어 Windows용 PSTrace 소프트웨어 뿐만 아니라 Android 용 PStouch app으로도 장비 제어가 가능합니다.
완벽한 실험용 장비로 휴대성이 간편하고 견고한 디자인으로 현장용 실험에 이상적인 장비입니다.

PalmSens4는 광범위한 corrosion analysis methods를 가능하게 합니다. Tafel slope, 부식 속도, 부식 전류를 얻기 위한 polarization curve는 전기
도금, 증착 필름 또는 강제 부식을 일으키기 위해 표면에 전류를 가합니다. 또한 0.1 μHz ~ 1 MHz의 EIS (Electrochemical Impedance Spectroscopy)를
수행할 수 있어 coating resistance, polarization resistance, pore resistance, coating capacitance, coating의 수분흡수 및 고장수명을 예측할 수 있습니다.
