GL820 Midi Data Logger
Graphtec Recording Device for Voltage, Temp, Humidity, Logic and Pulse w/ Multifunction Input
The Graphtec GL820 is a compact, lightweight multi-channel Data Logger. The standard
configuration has 20 isolated input channels and can be expanded in 20 channel increments up to a total of 200 channels.
The GL-820 features a high resolution 5.7" TFT color display and an easy to navigate menu system for in-field changes to set up parameters.
Data can be captured in a variety of ways. Save directly to the 2GB internal flash memory or to a hot swappable USB memory stick. You can also save directly to a network drive via Ethernet or to a PC via USB cable. The Web & FTP server functions built in to the GL820 allow for control and monitoring and data transfer from a remote location.
