Description

The Graphtec GL820 Data Acquisition Data Logger is a 20 channel portable data logger. Contains an insulated system which ensures signals do not cause any distortions among other channels. Suitable for recording voltage, temperature, humidity, pulse and logic signals.

The 4GB Flash Memory enables a secure long term data measurement usage without applying an external storage device. The GL820 supports USB 2.0 memory sticks for external storage. The GL820 saves measured data directly on to the USB memory sticks. The USB memory stick can be replaced during measurement without loosing any data. The 5.7 inch TFT color LCD provides the ability to read data in waveform and digital forms to measure and analyze data in real time.

The GL820 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 GL820, 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.
