Description

The VersaLog VL-DCVC Voltage Current Temperature Data Logger

The VL-DCVC Voltage Current Data Logger is an 8-channel, battery-powered, stand-alone voltage, current, and temperature data logger. It records up to 8 megabytes of data and stores it in non-volatile flash memory for later retrieval. Input voltage/current signals can be from sensors, transducers, transmitters or any other common voltage/current sources. Its on-board temperature channel provides environment monitoring and temperature compensation.

Featuring an aluminum enclosure and conformal coating PCB, the logger has excellent performance in the harshest industrial environment. Powered by a 16-bit ADC and programmable input range, the logger is well suited to science and laboratory applications where precise and accurate measurement is critical. Simplify communications and engineering unit conversion with the Plug & Play USB port and versatile custom equations. Simply plug the logger into a computer’s USB port, and the software automatically recognizes it and handles the configuration, downloading, graph viewing, and more
