This Data Logger Requires IFC200 USB Cable & Software Package.

The OctVolt DC voltage data logger is a standalone device, featuring eight channels and is battery powered. This portable, all-in-one compact device is easy to use and is capable of measuring and recording up to 16,383 measurement readings per channel.

This device accepts voltage signals from sensors, transducers and many other common voltage sources and features user-programmable Engineering Units and offset/gain calculations so input voltages can be scaled to proper units being measured. For example, a flow rate sensor with a voltage output can be displayed as flow rate in the software graph and data.

The OctVolt makes data retrieval quick and easy. Simply plug it into an empty COM or USB port and the user-friendly software does the rest. Four different voltage ranges are available, 2.5 V, 15 V, 30 V and ± 100 mV. The ± 100 mV model features differential input capability.

Readings are stored in non-volatile solid state memory, which provides maximum data security. The device can be started and stopped directly from the MadgeTech Software and its small size allows it to fit almost anywhere.
