Web-Thermograph 8x Pt100/Pt1000

Monitor and graphically display up to eight temperatures


Measure, log and report...

The Web Thermometer 8x is an instrument that measures 8 temperature points and makes the values available in the network. The device includes an integrated data logger and numerous Web and network services for manual querying of the measurements or provides autonomous sending of messages.

Example application:



  • Eight measuring inputs Pt100/Pt1000:
    • Measuring range of W&T probe: -50°C...180°C
    • Measuring input: -200°C...650°C


  • Intuitive Web interface for simpler configuration
  • Monitor temperatures and trends from a browser
  • Alarm and reporting function:
    • E mail for alarm or as reporting function
    • SNMP polling / alarm traps
    • Configure up to 12 alarm messages
  • Dynamic integration into other Web sites:
    • Direct access to current measurement values, e.g. JavaScript (AJAX).
  • Current Industry 4.0 protocols:
    • REST and MQTT support
  • Additional software interfaces for incorporating into your systems/databases:
    • OPC server
    • Syslog
    • Sensobase (database integration via ODBC)
    • TCP and UDP sockets, client and server
    • FTP (data logging)
  • Possible applications:
    • Monitor temperatures in the server room, network cabinet or office
    • Direct display of multiple measuring points in the browser via Java applet
    • Logging of measurements via FTP, Excel file, email attachment and internal memory
    • Green IT: Monitor efficiency of the server room climate control
