The Graphtec GL220 10 Channel comprehensive Portable midi 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.

10 Channel Comprehensive midi LOGGER - By connecting the Graphtec GL220 to a USB memory stick, the user can use 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.

An optional battery pack is available for portable use. The battery pack allows up to 6 hours of operation. The Graphtec GL 220 is supplied with PC application software. The Graphtec GL-220's software allows for real-time waveform monitoring as well as data upload and data export to spreadsheets such as Excel. Hot-Swap linked function can be performed when capturing to the external USB memory drive. The Graphtec GL/220 captures directly to the PC can now be performed at a speed of up to 100ms (sampling rate).

LCD Screen Operation - The bright easy-to-read 4.3" colour LCD screen of the Graphtec GL220 makes it even easier to review measurement settings, measured waveforms and digital values. All the Graphtec GL 220’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.

Software - The Graphtec GL220 is supplied with software that provides excellent control over most GL Series functions. The Graphtec GL220 also provides convenient data transfer and control from your PC to the Graphtec 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 Graphtec GL-220 channel count can now be increased by connecting up to 10 Graphtec GL220 to a personal computer running the Graphtec GL 220 control software. Software can also be used with the Graphtec GL800 simultaneously with the Graphtec GL220.
