Graphtec GL220 10 Channel Data Logger
Graphtec GL220 data logger accepts voltage, temperature, humidity, pulse and logic signals. Channel-to-channel isolation means wiring errors or overloaded channels do not affect neighbouring channels. Sensors are connected via rear mounted screw terminals. The built-in 2GB memory is non-volatile so that data is retained even if the power supply is interrupted.
Connect a USB memory stick to the USB for additional data storage. With a 512M device, users can capture data for up to 269 days (10 channels, 1 second sampling rate). Connect a PC through the USB Type B port for direct data capture to PC, data transfer and control.
