If you’ve ever had to deal with fuzzy or poor quality bio-potential waveforms, then you know how difficult and frustrating this process can be. EIM-107 Prep-Check Plus, a handheld multi-lead electrode impedance meter, is the leading choice for researchers, cardiac centers, sleep centers, physicians, and monitor and electrode manufacturers, around the world. Use Prep-Check before an ECG/EEG to ensure electrodes, lead wires and cables have a proper connection. Studies show that proper electrode site preparation can reduce baseline wander, 60 Hz interference and movement artifact that compromise ECG/EEG reports costing time and money. With Prep-Check, better EEG & ECG readings the first time results in higher quality studies and reports at less cost.
