The Graphtec GL220 Data Acquisition Data Logger accepts voltage, temperature, humidity, pulse and logic signals. Channel-to-channel isolation means wiring errors or overloaded channels do not affect neighboring channels. Sensors are connected via rear mounted screw terminals. The built-in 4GB 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. The GL220 is supplied with PC application software. The software allows for real-time waveform monitoring as well as data upload and data export to spreadsheets such as Excel.

The bright easy-to-read 4.3" color LCD screen makes it even easier to review measurement settings, measured waveforms and digital values. All the GL220's functions can be accessed through the navigation cluster and LCD screen. Single touch buttons for such tasks as display mode, setup and logging start/stop negate the need for complicated menu trees.

The GL220 is supplied with software that provides excellent control over most GL Series functions. It also provides convenient data transfer and control from your PC to the GL220, as well as converting measured data into file formats that can be used with spreadsheet applications, data analysis applications, and other software programs. Converted data can be easily processed in electronic spreadsheets and graphs using popular applications such as Excel.

The GL220 channel count can now be increased by connecting up to 10 GL220 to a personal computer running the GL220 control software. Software can also be used with the Graphtec GL800 simultaneously with the GL220.
