Large Capacity Connectible 4-Channel Loggers for Voltage

Voltage loggers with 4 channels on a single unit. Connecting multiple loggers makes it possible to measure and record 16 channels simultaneously.


The MCR-4V is a 4-channel battery operated logger that measures up to 24V. With its large internal memory (up to 480,000 readings per unit) and multi channels, it is perfect for measuring voltage and current signals at various spots for long periods of time. Moreover, by using an SD card and the “Auto Data Export” feature recording can be carried out, even when using short recording intervals, over longer extended periods of time.

MCR-4V loggers operate on battery or USB power and can download data to a computer. The software allows you to view and analyze the data. You can connect up to four loggers, including our MCR-4TC temperature data loggers, allowing for up to 16 channels of data. This coupled with the fact that the loggers are equipped with an SD memory card slot means they are perfect for use in various experiments with large quantities of data and for tracking frequent changes in voltage and current.
