Joulescope JS220 Precision Energy Analyzer (JS220-K000)

Our next-generation affordable and easy-to-use instrument enables you to create better, more energy-efficient products. Measure current from nanoamps to amps while simultaneously measuring voltage, power, energy, and charge.

Measuring energy consumption during product development is crucial, especially for battery powered and always-on devices.  However, measuring energy consumption accurately has been expensive, tedious or error-prone.

Joulescope measures current and voltage, then computes power, energy, and charge.  Joulescope™ enables designers, engineers, and makers to quickly and easily optimize the energy consumption and battery life of a target device. Joulescope is designed to automatically handle wide current ranges and rapid changes in energy consumption, while allowing the target device to run normally.

View instantaneous values

Joulescope captures and displays the instantaneous current, voltage, power, energy, and charge, like a multimeter.

View waveforms over time

View changes over time, like with an oscilloscope.  Navigate through your data, select regions of interest, and explore where your device uses the most current and power.

All on your computer.

Joulescope connects entirely using USB with no external power adapters.  The software is free and open source.  Easily navigate your data using a mouse and keyboard.
