Document measurement data online

Measure and visualize temperature, relative humidity and air quality

Cloud Measurement Data

Continuous availability everywhere

Continuous documentation of the measurement data in the online memory enables access to the measurement data anytime and anywhere.

Automatic documentation

The W&T Web Service makes long-term automatic documentation of measurement data possible. No more time-consuming recording and loss of important measurement data.

Individual visualization

Views can be individually created and charts and measurement curves combined as desired.

Current graphs from different locations can be conveniently compared with each other, discrepancies quickly noted and views shared with other cloud users.

Web-Thermograph from W&T


Connect W&T Web-Graph to the network

  • Install sensor

  • Connect power supply

  • No configuration on the device is necessary since it is automatically given access to the network via DHCP and can connect to the cloud service.

Measuring data local or online

  • Measurement values are stored directly on the sensor and can be viewed when needed in the browser (without the cloud). Limit violations are reported and indicated on the LED ’traffic light’ of the device (Web-Graph Air Quality model only).

  • Optionally you can automatically send the measurements from the device to the W&T cloud, save and document them there and report limit violations.
  • Then simply:
