Overview
The SPA120 is a highly sensitive instrument combining sensitivity, accuracy, and stability for low-current measurement across two fully isolated channels. Designed for scientific and research applications including physics, materials science, and electron microscopy.
Features two synchronised, independent channels with series-linkable sources reaching ±80 V bias voltage. Connects via USB and runs with the free EPIC software for measurement graphing, data capture with timestamps, and stability monitoring.
