Which one to choose
Otter I-V
If an undergraduate lab needs several units
Suited to classes where student groups measure at the same time. Commodity devices go straight onto the breadboard, so preparation is light, and lab handouts are supplied.
Otter I-V Expert
If a research group needs to characterise devices
Suited to measuring small currents through a probe station, or to the repeated characterisation of memristors and synaptic devices. It also covers measurements that need high voltage.
