Voltage Data Recorder and Logger
TandD VR-71 Records Voltage with a Measurement Range of ±15 Volts DC
 The voltage data recorder data logger measures and records voltage signals within a measurement range of DC(±) 15V. It can record signals of 1-5V / 4-20mA as welll 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 measurings.
Each Voltage Data Recorder Includes
>> (2) VR-7101 Input Cable
>> VR for Windows Software and User Manual
>> (2) AAA Alkaline Batteries
>> RS-232C Serial Communications Cable
NOTE: Large Quantity Discounts available!
