Multi Channel Voltage Recorder

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.

Features

  • 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 10µV 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
