MadgeTech OctVolt

The OctVolt is an eight channel, battery powered, stand alone voltage data logger. It accepts voltage signals from sensors, transducers and many other common voltage sources. The software 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. Four different voltage ranges are available. (±100mV model features differential input capability).

A MadgeTech software and cable kit is required for operation. The easy-to-use MadgeTech software features enhanced tools like the use of engineering units, digital calibration, and automatic export to MS Excel.
