Our highly sensitive source picoammeter is designed for measuring and logging very small currents down to the pA range - making it an ideal instrument for scientific and research applications, including physics, materials science and electron microscopy. Full-featured at an affordable price, the SPA100 combines sensitivity, accuracy and stability to allow users to measure low currents with high precision as well as conveniently source bias voltages for experimentation. SPA100 also doubles as an ultra-high resistance meter, measuring accurately into the teraohm (10^12) range. As with all our “headless” products, the SPA100 connects to PC via USB and utilises our complimentary software SPA - enabling users to easily measure, graph and capture readings with timestamps and measurement stability information. Features & Specifications Input: +/-2mA to +/-200pA in 8 ranges. Accuracy and Resolution (2Hz): +/-2mA range: +/-0.1%, resolution
