Otii Ace Pro

Connect several Otii Ace Pro devices in series and parallel to increase voltage capabilities. Measure systems where battery negative terminal is not the system ground. Measure with your energy source (for example your battery or energy harvester) in series while switching between measurement ranges.

Measure accurately over 9 orders of magnitude from amps down to tens of nanoamps with the wide dynamic range of Otii Ace Pro.

Display and work with accurate visualization of the active and sleep modes on the same screen and in the same project. 

Otii Ace Pro is a 2 quadrant source measure unit (SMU) with a constant voltage/constant current source and sink and a high precision multichannel multimeter.

It provides less than nA resolution current measurements with adjustable sample rate up to 50 ksps. The high sample rate and low step size enable accurate analysis of current consumption and inrush current.  

Current measurement sample rate for Otii Ace Pro is adjustable. 

Otii Ace Pro has active voltage regulation and compensates for burden voltage.

Otii Ace Pro measures 10,9cm x 14,4cm x 4,4cm (WxLxH) and weighs 450 grams, just as Otii Arc. It is designed for the office, the lab, and usage at home, as well as field measurements. Also, the innovative mechanical design allows for efficient heat dissipation, hence no fan is needed and therefore no noise. 

Power it by USB C.

Otii Ace Pro is NIST-traceable calibrated before leaving the factory.

Otii software runs on macOS, Windows and Ubuntu. It is build for ease of use, accessibility and durability for those long measurements. 

With Otii Automation Toolbox you can control your Otii box with the built-in TCP-server from any language or system that supports communication over TCP sockets, using a JSON-based API. Find more automation and scripting capabilities here. 

With additional Otii Battery Toolbox license you can elevate your Otii hardware and use it for profiling of batteries and PV cells, emulation and cycling of batteries.
