Announcing the New Multi Channel Voltage Recorder: MCR-4V

T&D Multichannel Recorder MCR-4V is a 4-channel battery operated voltage data logger. Up to 4 units can be coupled together, making it possible to simultaneously measure and record up to 16 channels.
Quick and precise measurements are made possible with a shortest recording interval of 2 msec, and a minimum voltage resolution of 10 µV.
Besides using a USB connection to directly send recorded data to a PC, it is possible to use an SD card to transfer data from a logger to a PC. Data can also be viewed and checked on the handy LCD display.


  • Capable of 4-channel measurements and recording with a single unit
  • Simultaneous measurement and recording for up to 4 units (16 channels) by coupling units.
  • Runs on 2 AA Alkaline Batteries
  • Minimum Resolution of 10 µV and Input Range of ±24V
  • Recording Interval as short as 2 msec
  • Use of SD Memory Card for Data Transfer to PC
  • Logging Capacity of 480,000 data readings
  • Scale and Unit Conversion for each channel
  • Electrical Isolation between channels
  • Use of Trend Graph for Checking Data in Real Time

Ejemplos de aplicación

  • Measure and record data for control devices and measurement instruments in factories
  • Record signals from actinometers, anemoscopes, rain sensors and CO2 meters
  • Record output signals from a variety of sensors and analyzers
  • Measure voltage in electrical circuits

  • *1 : When "Auto" is selected, measurement range will be automatically changed according to the voltage being measured.
  • *2 : If the logging capacity is not filled at the end of one recording session, the logger can record up to 30 times.
  • *3 : A memory card can be used to transfer recroded data from a logger to a PC. However, measurement data cannot be directly recorded into a memory card.
  • *4 : Battery life varies depending upon the frequency of communication, wireless LAN environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
