Precise-Log 8-Channel Voltage Data Logger

The PRECISE-LOG PL-VW is an 8-channel, battery powered, standalone and WIFI-enabled voltage data logger. The logger records eight external voltage sources and saves data in 8-MB memory.

Its aluminum enclosure makes it excellent in the harshest industrial environment.
Embedded WIFI module allows remote data monitoring and downloading. 16-bit ADC makes it well suited for science and laboratory applications where precise and accurate measurements are critical. Features: – 16-bit analog-to-digital converter- 8 megabyte memory size- Both USB and WIFI comm. interfaces with baud rate of 115200 bps- Programmable input ranges (5 VDC, 20 VDC)- Over 10 years of battery life- Powerful software for configuration, downloading, plotting, analysis and alarm reporting- Wide sampling interval selections (one second to 12 hours)- Rugged aluminum enclosure
