Having flexible and versatile system that embeds data acquisition needs into various types of R&D environment helps developers and researchers with solution that eliminates the testing turn around significantly.  Graphtec’s datalogger and data platform focus on this versatility aspect of the test & measurement by providing a portable system that takes you from one test to another with relative ease.  Our focus is recording and analysis of low-voltage signals including physical sensors as well as temperature sensors along with advanced test and measurement applications as well as high voltage analysis for AC and DC signals up to 1kV.  From strain measurement to accelerometers as well as pressure transducers to pH meters, scale the input from your proprietary signals to record your signals for long term and/or dynamic transient analysis.




Portable configuration of Graphtec Dataloggers puts data acquisition and signal analysis at the palm of your hand with time-stamp view of the real-world signal.


Physical sensors with linear voltage output (or 4-20mA loop) can be displayed individually with its original unit of measurement.


Forget about spending weeks and months for setting up Automated Test System to configure the next scenario that takes so long to build.  Set up your test scenarios within minutes using the Graphtec GL dataloggers.
