Graphtec Data Logger GL200 midi LOGGER

Supplier: Lontek

The multifunction GL200 data logger accepts inputs form voltage, temperature, current*, humidity, pulse and logic signals. This allows combined measurements, even for disparate phenomena such as temperature/humidity and voltage. *External shunt resistor required.


With an isolated input system the GL200 ensures that cross channel interference is minimised and this eliminates the need to pay special attention to wiring which allow users to speed up their data logging tasks.

Accepts USB memory devices of up to 1GB capacity

Two ports are provided on the GL200, one for the plug-in USB memory device and one for connecting to a PC.

Commercially available USB memory devices may be used for direct capture of data or to transfer data to a PC. With a 512MB USB memory device, users can capture data for up to 269 days*. In addition, the GL200 can be connect directly to a PC via the USB cable which allows data to be transferred or measurements to be stored directly to the PC for data logging.
* 10 channels, 1-s sampling rate.

Built-in flash memory for reliable measurements

The flash memory used for the built-in memory device ensures that data is retained even if the power supply is interrupted. This means momentary disruptions in the AC power supply or accidentally switching off power will not result in data loss even while data logging.

User –friendly design

The GL200 incorporates feature such as the ability to set measurement parameters for each item separately and navigation assistance to provide superior operability. The device case features stylish non-slip rubber.

Vivid 9cm (3.5") TFT colour LCD

The bright, easy-to-read 3.5-inch TFT colour LCD monitor makes it even easier to review measurement parameter settings, measured waveforms, and digital values. All the GL200'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.

6 hours of continuous battery operations

A convenient optional battery pack is available for use in areas where AC power is unavailable or subject to interruption. The battery pack enables 6 hours* of continuous measurement and provides a remaining battery capacity display function. * Varies with measurement conditions.

Free Bundled PC software

The GL200 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.
