Affordable precision DC energy analyzer launches
Engineering services company Jetperch (Olney, MD) has launched an affordable test instrument that it says empowers engineers to develop products with increased power efficiency and longer battery life.

Joulescope, says the company, is the first affordable test instrument that can measure the wide dynamic current range of new products with precision and accuracy. The Joulescope JS110 precision DC energy analyzer is designed to enable engineers to quickly and easily identify and fix the parts of their designs that consume too much energy.

"At numerous times during my career and across different projects, I struggled to accurately and affordably measure current and energy consumption," says Matt Liberty, the creator of Joulescope. "Having easy access to this information during product development is crucial, especially for battery-powered devices. After two years of development, Joulescope is now ready to empower engineers to create better, more energy efficient products."

The company says the Joulescope offers the following features:

  • Superior dynamic range: Measures electrical current from amps down to nanoamps.
  • Low voltage drop: Maintains under 25 mV to keep the target device operating normally.
  • Makes the invisible visible: Simultaneously measures current and voltage two million times per second with 250 kHz bandwidth to display short events including interrupt service routines and inrush currents.
  • Easy to use: Provides a simple multimeter instantaneous view and an oscilloscope view showing changes over time.
  • Customizable: Includes open source software and a swappable front-panel that allow users to adapt Joulescope to their needs.
  • Portable: At just 150 mm x 81 mm x 33 mm (5.9" x 3.2" x 1.3") and 217 grams (0.5 lbs), fits conveniently on the desk and can travel.
  • Multiplatform support: Works with Windows, macOS, and Linux.

"With a Joulescope at their desk, developers get immediate feedback on the impact of their changes," says Liberty. "Products designed with a Joulescope are more environmentally friendly and have batteries that last longer between charges and replacement."

Joulescope started as a successful Kickstarter campaign that raised $106,347 in March. The Joulescope JS110 is available immediately at the Joulescope store for $699 through July 26th, a $100 discount off
