TandD VR-71 Voltage Data Logger

The VR-71 data logger is designed for measuring and recording voltage signals. The measurement range is DC ±15V and can record common signals, such as 1-5V / 4-20mA as well as output signals from a variety of sensors. Its most impressive feature allows the creation of your own dot matrix patterns for unit display and the ability to convert the recorded voltage signal into the desired unit and display accordingly.
