Recorders and indicators display, log, and archive process data for analysis and regulatory compliance. Paperless recorders store large volumes of digital data and support USB or Ethernet export, while chart recorders provide hardcopy trend visualization. Indicators display real-time readings of temperature, pressure, or flow in both analog and digital formats. These devices are critical for process validation, maintenance planning, and quality assurance. Modern recorders feature touchscreen interfaces, remote access, and integration with SCADA or ERP systems.
