Centralized Monitoring: Use our Ethernet enabled EDL-Net data loggers to enjoy real-time temperature data collection and monitoring at anytime, from anywhere in the world over a local network or via an internet connection. Leverage your existing LAN with the built-in RJ-45 jack for CAT-5 LAN, or an Ethernet-to-WiFi bridge for WiFi connectivity to avoid expensive installation costs for managing temperature data. Marathon's Ethernet enabled loggers will allow you to monitor multiple floors, buildings, rooms and locations simultaneously.Certified Safe Storage
Our advanced software can be programmed by the user to detect high and low temperature excursions, or power outages, and trigger audible and visible alarms as well as send alert notifications via cell phone and/or e-mail for facilities management control.
Marathon's 21 CFR: Part 11 compliant software, with secure supervisory controls, will allow database creations for products, part numbers, dates, locations, identification numbers, statistical analysis, and more.
In the lab, our NIST-calibrated and traceable thermistor probes have been tested sterile and can be used in incubators. In hospitals, clinics, pharmacies and blood banks, the EDL-Net is perfect for quality assurance and quality control, monitoring low temperature freezers, blood storage, vaccines and biologics via state-of-the-art high-performance temperature sensors and data logging.

  • Alarm notifications via cell phone or pager
  • Interchangeable sensors:-80 C to 72 C
  • Multiple Alarm options: local and remote
  • Precision temperature data capture
  • Powerful software with real time display
  • Audit Trails for Regulatory Control
