All channels Isolated with Universal inputs
With an isolated input system, the Graphtec GL240 ensures that cross channel interference is minimised. This can eliminate the need to pay special attention to wiring which allow users to speed up their data logging tasks.
The Graphtec GL240 data logger can accept various inputs ranging from voltage, thermocouples, process 4-20mA*, humidity, pulse and logic signals.
*External shunt resistor required.
Voltage |
20mV - 100V , 1-5 V for process 4-20mA. |
Thermocouple |
Type: K,J,E,T,R,S,B,N,W. |

Supports large-size SD memory card for reliable long term measurement
The Graphtec GL240 data logger supports two SD memory card slots for data storage. The SDHC type SD memory card is supported up to 32GB. A 4GB SD memory card is supplied as a standard accessory and installed in the first SD memory card slot.
Binary or ASCII data file types
The captured data can be stored in GBD(Graphtec binary data) or CSV file format. The binary data format is more robust and a lot more compacted than the CSV format. The CSV format has the direct advantage in that it can be opened directly in MS Excel or other data analysis software programs.

Vivid 10.9cm (4.3") TFT colour LCD
The bright, easy-to-read 4.3-inch TFT colour LCD monitor(WQVGA: 480 x 272 dots) makes it even easier to review measurement parameter settings, measured waveforms, and digital values. All the GL240'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.
Free Bundled PC software
The GL240 data logger is bundled with PC application software that enables measurements directly with a PC. In addition to waveform monitoring, this software provides other useful functions such as direct writing of data to an Excel file and report creation. The software also provides a Help display function for enhanced usability.
