Issues from maintenance problems with heavy industrial and multi-million dollar manufacturing equipment can cause hundreds and thousands of products to be delayed in production.  Graphtec dataloggers offer handy portable trouble-shooting tool for testing and monitoring electrical signals from expensive industrial equipment. From condition monitoring to life cycle testing, embedded Graphtec solution can offer multi-various inputs displayed in large format with easy-to-handle data from complex data acquisition to simple thermal verification processes.

Rapid installation of the test platform can offer in-depth diagnosis of CNC machines, presses, rollers, mills, and even tractors and 3D cutters and printers.  Monitoring long term condition of heavy equipment can also offer analysis on asset conditions and motor performances to measure durability and uniformity of production and manufacturing.  Protect your asset with Graphtec dataloggers to measure and to prevent failures and catastrophic events.




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


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


Graphtec recorders offer low-cost alternative to ATE setup where roll out and engineering require significant labor.
