- Computer-Free Operation (Untethering)
You can disconnect your computer from the VIONIC potentiostat while an experiment is running—without any data loss. All measurement data (up to 10 million data points) is securely stored within VIONIC and can be seamlessly transferred back to your computer once reconnected. INTELLO also indicates how long you can keep the computer untethered during the experiment. - Data safety
INTELLO protects your data by saving it automatically and continuously to user-defined location during experiment - Cell safety and protection
User-defined rules, cutoffs and cell safety protection limits for your cell and instrument safety - Seamless measurements
