Measurement and control technology

We supply external and built-in temperature recorders in robust metal or plastic housings, suitable for various applications.

Depending on the requirements, 6-, 12- or 24-color recorders are available, enabling precise and clear temperature documentation.

As a manufacturer, we produce the devices according to your individual specifications or in proven standard designs – reliably, precisely and practically oriented.

WG-STAR program temperature controller

WG-STAR program temperature controller

Our programmable controllers feature a unique 6-phase configuration. A highly intuitive user interface makes operation incredibly easy. Individual parameters can be programmed, queried, and modified during operation using just four buttons.

We also included a specific alarm function for control via an optical or acoustic signal transmitter.


Whether fast or slow heating rates, one or more holding times, cooling or heating phases – you determine the individual process on the device.

GRUBE LogOnline - System

GRUBE-LogOnline offers temperature monitoring and backup via the Internet.


The AL temperature recorder sends the measured values to the data server for storage at short intervals.

The measured values can be accessed at any time using your personal password on your smartphone, tablet, or PC via the homepage of Wärme- und Glühtechnik GRUBE GmbH.

  • permanent data backup in the cloud

  • Location tracking via GPS (theft protection)

  • Tamper-proof thanks to the DATA server

  • Alarm function via email or SMS

  • Labeling of the logs via the web interface

  • Data export as PDF or CSV is possible.

  • Print diagrams directly or save them as JPGs.

In addition to the analog printout on paper, the temperature recorder also offers the option of saving the data to an SD card.
