Graphic recorders
Graphic recorders allow simultaneous viewing and recording of analogue or digital signals over long periods. Versatile, they combine multi-channel acquisition, high-resolution A/D conversion (16 to 24 bits) and real-time graphic display. In R&D, they are used to observe slow or cyclical changes - temperature, voltage, current, pressure, torque - and to validate the stability of a system. In production, they monitor process quality, critical thresholds and performance drifts. In maintenance, they capture transient events, voltage drops or cycle interruptions. Modern models offer extended internal memory, USB or SD card storage and LAN/Wi-Fi connectivity for remote monitoring. The high-resolution display and cursor control allow fast, accurate analysis. SCPI or Modbus compatibility makes it easy to integrate into automated test benches. Used in the energy, aeronautics, research and process industries, these recorders guarantee traceability of measurements and reproducibility of tests.
The ideal tool for visualising, documenting and archiving changes in physical quantities over time.

concrete questions about Graphic recorders
01
What is the function of a graphic recorder?This is a device that measures and plots analogue signals (voltage, temperature, current, etc.) in real time on a screen or thermal paper. It can be used to directly display changes in physical parameters over a given period.
02
In what environments are they used?These instruments are common in industrial environments, in test laboratories, power plants or production lines. They are used to monitor drifts, validate cycles or record transient events.
03
What's the difference with a central purchasing unit?The graphic data logger is a stand-alone device designed for display and visual traceability. It is often less modular, but easier to deploy for continuous measurements or event-based monitoring.
04
What criteria should you use to compare two models?Display resolution, number of analogue or digital channels, recording time, trigger modes, data export formats and whether or not a paperless recorder is available.
05
Can the data be recovered for computer analysis?Yes, most modern models have a USB port or Ethernet access for transferring files to a PC. Some also offer CSV or PDF export, or compatibility with dedicated analysis software.
