The Web-Thermo-Hygrometer ++ is a self-running datalogger for temperature and humidity. Data access and configuration are done via the web browser. Depending on the storage interval, the Web-Thermo-Hygrometer ++ records data from measurement periods of between 12 weeks and 20 years.

The humidity sensor used shows no signs of saturation when used permanently in a humid climate, thus allowing precise measurements, for example in nurseries, ripening rooms, in fruit and vegetable stores as well as in various applications for the textile, wood or paper industry. Furthermore, the Web-Thermo-Hygrometer ++ is suitable for outdoor use. On request, the device will be delivered with an additional calibration certificate (ISO or DAkkS).

If critical conditions occur, such as high or low values that have been exceeded, the device triggers configurable actions. These include the sending of alarms via e-mail, SNMP trap and / or the IoT protocol MQTT.

A multitude of communication protocols allows uncomplicated integration in SCADA, network management or MES systems. MQTT and REST provide protocols for connecting to the Internet of Things and for use in the area of Industry 4.0. The development of individual solutions is also supported by access to network sockets and the HTTP interface.

The drift-free Web Thermo-Hygrometer ++ is now available for a net price of € 1298.00. Commercial users can try the device for free for a period of four weeks.
