Description

The VersaLog VL-DCV-2 Voltage Data Logger

The VL-DCV-2 Voltage Data Logger is an 8-channel, battery-powered, stand-alone voltage data logger. The logger records up to 4 million readings of data and stores it in non-volatile flash memory for later retrieval. Input voltage signals can be from sensors, transducers, transmitters or any other common voltage sources.

Featuring an aluminum enclosure, the data logger has excellent performance in the harshest industrial environment.

Powered by a 16-bit ADC and programmable input range, the data loggers are well suited to science and laboratory applications where precise and accurate measurement is critical.

Memory Capacity

The DCV-2 voltage data logger comes with 8MB onboard flash memory. The following table shows the relationship between the number of enabled channels, sampling interval and max time span of logging.
