“I love my Otii Arc! Next to a scope, this is the best piece of test equipment an embedded hardware/software developer could want. Micropower measurements are a breeze and it replaces my power supply as my go to power source and analyzer. Small, precise, and portable this thing goes anywhere I need to go.“

Peter Sterrantino, Sr. Principal Engineer at Stryker

“Can’t imagine firmware development now without using an Otii Arc, and Otii Automation Toolbox allowed us to automate our production power profiling during the final test.”

Mathew Key, CTO at Isansys

“Thanks to Otii, we have been able to reduce our Strips current consumption even further to reach more than 10 years battery life. Every developer should have Otii Arc.”

Mats Pettersson, CTO at Sensative

“Working with Qoitech and establishing this low-power mindset certainly enriches the LoRaWAN community.”

Wienke Giezeman, CEO at The Things Industries

“If you are looking into optimizing your IoT device for low-power design, reach Björn Rosqvist from Qoitech, I cannot express how much energy we saved with the Otii Arc.”

Tal Klinger, Hardware & System Engineering Team Lead at Trax Retail

“If you are doing anything, designing IoT devices, battery-driven devices, handheld devices or anything that uses power where you want to be conservative about the power get this device – it just works for you! Easy to use, out of the box and state of the art.”

Ole Valeur, Senior Global Application Engineer at Okdo

“My favourite developer tool is the Otii and the feature that I like the most is the UART log which is combined with power consumption display – it is wonderful to see AT commands running through the module and triggering the power peaks.”
