T&D VR-71 Voltage Data Logger

  • 2-channel voltage logger
  • 4 measurement ranges per channel: ±1, ±2, ±6, ±15
  • 20 programmable measurement rates from 20 Hz to once per hour
  • Programmable scaling and display units
  • Stores 8000 points/channel
  • Includes Windows software to setup, monitor, download, graph and export data



The TandD VR-71 data logger measures and records voltage signals within a measurement range of DC (±) 15V. It can record signals of 1-5V / 4-20mA as well as output signals from a variety of sensors. The most impressive feature is the software function that allows you to create your own dot matrix patterns for unit display and then change the recorded voltage signal into the desired unit and display accordingly to match your measurements.
