HTK 8Our range of laboratory furnaces is completed by the model HTK 8. The furnace is designed so that with selectedattachments it is possible to assemble the furnace to perform different processes utilising various atmospheres,vacuum and application temperatures.

The model can be used for sintering metal carbides, such as tungsten carbide. However, it can also be used forsintering oxides or non-oxide materials in defined atmospheres. Also coarse, fine and high vacuum applicationscan be performed with the HTK 8. Have a word with us tor further details!

heating with either molybdenum disilicide (Mo Si2), molybdenum or graphite heating elementsgassing installation with rotameter for non-flammable process gases includedvacuum pumping for atmosphere changes and for rough vacuum applications, including pressurerange 10 –2 to 10 –5 mbar (depending on the model)numerous accessories available on requestavailable for Tmax 1600 °C, 1800 °C or 2200 °C

As an option, we equip our furnaces with a temperature selection limiter for protecting the materials andfurnace. Should the furnace exceed the safety temperature that has been set, this safety regulator switches off theheating of the furnace.

Software for monitoring, documentation and controlDocumentation and reproducibility are gaining more and more importance for the quality assurance in thelaboratory area. Here, the powerful software Controltherm developed by us provides you with the optimumsolution.Features:
