facts about us


electrotherm GmbH of Geraberg was founded in the year 1991. The region around Geraberg, situated in the green heart of germany, is a traditional centre of the german glass and thermometer industry and well known for liquid-in-glass-thermometers, laboratory and precision thermometers.


Now we produce resistance thermometers and thermocouples for a wide range of applications in industry and science. Major applications are in the chemical industry, in plant engineering, the interior of large-scale diesel engines, in power and heating installations, in agriculture, the food industry, storing and calibration services and standard laboratories.

A number of temperature sensors have been granted special certificates, such as GL for ship-building or ATEX for explosion-protection. Continuous monitoring of the manufacturing process and stringent testing of the finished products ensure compliance with DIN EN ISO 9001:2015 and other international standards. 

Additional to the industrial thermometers we can offer high precision thermometers for applications in R&D. Components and accessories like protective tubes, means of fastening or transmitters complete our product range.
