Electronic test and measurement work is increasingly required to complete with faster deployment and quick turnovers as new products are being rolled out with a shorter development cycle.  Testing professionals are required to reduce the cost of testing yet still cover the ground for accurate and precise measurement for complex analysis of mixed signal measurement such as vibration, temperature, strain, pressure and other variables. 

Graphtec’s portable and standalone dataloggers offer flexible test system that troubleshoots the most complex scenarios where mixed variable recordings are necessary to measure inter-dependency between various signals.  Easy-to-display time stamp view of the trend analysis allows up-to-the-second view of your measurement at the palm of your hand.  From lab-based benchtop testing to in-production electronics testing for multichannel measurements, GL series dataloggers and data platform provides the most accurate and well-tuned noise-protected signal analysis giving you the confidence to design and to build strong and stable electronic devices. 




Portable configuration offers easy-to-use troubleshooting tools for using dataloggers in various test conditions.


Set up your next test scenarios within seconds using condition files for your mixed signal measurement.


Graphtec recorders offer industry-leading handheld multichannel datalogger as the most cost-effective solution in the market.
