Measure, log and report...

The Web-Thermo-Hygrobarometer is an instrument that measures temperatures, relative humidity and air pressure 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.

• Sensor:

  • Temperature sensor:
    • Measure range: -40°C...85°C
  • Relative humidity sensor:
    • Measuring range 0..100% RH, permissible ambient: 0..95% (non-condensing)
  • Air pressure sensor:
    • Measuring range 10-1100 hPa

  Connectivity:

  • Intuitive Web interface for simpler configuration
  • Monitor temperatures and trends from a browser
  • Alarm and reporting function:
    • E-mail for alarm or reporting functions
