Graphtec GL-240 [GL240] Compact Standalone 10-Channel Datalogger w/4.3 in. Color Display

Graphtec GL240 is a third-generation data logger product with exceptional price/performance. It’s a 10 analog channel device augmented by four discrete inputs and outputs. Its discrete inputs can be configured as a group to be either logic inputs or pulse inputs. When configured for pulse, each of the four channels can be configured to measure frequency or to count. The four discrete outputs are alarms that can be triggered by a variety of easily-defined analog and pulse/discrete input channel conditions. The 10 GL240 analog input channels may each be configured to measure a direct connected voltage in the range of 20 mV to 100 V full scale across 12 ranges, or for a direct-connected thermocouple of any type to measure temperature. Each of the GL240’s analog input channels is electrically isolated from other channels and from power ground allowing off-ground measurements using shunts, as well as powered or grounded thermocouples.

The most powerful GL240 feature is its triggering flexibility. Data recording can be independently started or stopped as a function of analog and pulse/discrete signal level (single or windowed), alarm, date and time, and day-of-the-week. Triggers can also be configured to operate only once, or to automatically repeat. The ability to of the GL240 to adapt to virtually any desired trigger condition allows the instrument to operate unattended for long periods of time with complete autonomy.

The GL240 operates either connected to a PC or entirely stand-alone. Connection to a PC may be over a standard USB or optional wireless connection. Either connection approach may take advantage of supplied PC-side software to configure, acquire, display, and record digitized information for storage directly to the PC’s HDD. Acquired data may be retrieved for review and analysis after recording, including the ability to export to Microsoft Excel. Using the GL240’s wireless option enables the instrument’s networking features, allowing it to be remotely configured and managed using the standard Web browser of any computer or smart phone. Automatic backup of data acquired to a user-accessible SD memory card is also supported via its FTP facility.

Finally, the measurement reach of a wireless-enabled GL240 is further extended by use of the GL100 accessory. The GL100 wirelessly enables measurements of temperature/humidity, acceleration, CO2, illuminance, ac current, and more. Communicate with up to (1) GL100 unit with B-568 Wifi module.
