Joulescope

Joulescope

Joulescope is a US-based manufacturer of precision DC energy analyzers designed for embedded systems developers and hardware engineers working on power-sensitive applications. The company's instruments simultaneously measure current, voltage, power, and energy with high dynamic range and automatic range switching, enabling engineers to accurately characterize the power consumption of battery-operated and low-power electronic devices without manual range adjustment.

The Joulescope JS220 series captures both high-frequency transients and long-duration energy measurements, making it particularly effective for analyzing devices that cycle between deep sleep and active operating modes — a common pattern in IoT sensors, wearables, and wireless communication modules. The instrument connects via USB and is accompanied by open-source software for real-time visualization and data logging.
