Otii Arc Pro is an instrument that can precisely source voltage or current and simultaneously measure voltage and/or current. It computes power and energy, and syncs with software output, enabling engineers and developers to easily see what drains the energy and optimize the battery life of their devices under test. Created by and for hardware and software developers.
The Otii Arc Pro is a small yet powerful measuring device that's 10.9 x 14.4 x 4.4cm (WxLxH) and weighs 450 grams. It provides a voltage of 0.5-5V and can measure current with a range of nA-5A and a resolution of 5nA, and it has a sample rate of up to 4ksps. You can connect it to your computer with a USB cable and use the Otii Pro software to analyze the measurements. The software works on Windows, Ubuntu, and macOS.
