Graphtec GL 220 Data Acquisition / Data Logger 10 Channel

Description

The GL220 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 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.

An optional battery pack is available for portable use. The battery pack allows up to 6 hours of operation.

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.

Hot-Swap linked function can be performed when capturing to the external USB memory drive.

Capturing directly to the PC can now be performed at a speed of up to 100ms (sampling rate).
