Otii Arc Pro

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

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

Otii Arc 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 tens of nAs resolution current measurements with sample rate up to 4 ksps, pending the current range. 

Otii Arc Pro has sample rates for three different current ranges up to 4 ksps. Voltage sample rate is 1 ksps. Check out datasheet for details. 

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

Otii Arc Pro measures 10,9cm x 14,4cm x 4,4cm (WxLxH) and weighs 450 grams, just as Otii Ace Pro. Both are 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 micro B. It can be powered by external power supply. Here are some suggestions for external DC supplies. 

Otii Arc 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.
