General furnace information

We sell laboratory furnaces of all sorts, but this page focuses on furnaces to be used with our products; ProboStat, Seebsys, CoulTCell etc. Also 1400ºC and 1600ºC versions.
Generic requirements
Suitable furnace for our products is a compact, table top, high temperature furnace with heated length 30 - 45 cm and opening on the bottom side with diameter of 40-50 mm. The inside top of the heated furnace should be 90 cm above the tabletop to be able to accommodate all possible arrangements. The furnace should preferentially be vertically mounted, but horizontal operation is possible in some cases.
If the furnace is meant to be controlled by measurement software, things get complicated quickly. For our software we use Modbus protocol, RS232 or RS485 wiring, and mostly Eurotherm controllers. There are other wiring configurations and data protocols that are used by other software manufacturers. To ensure compatibility with any measurement software, purchase your furnace from us. We will not provide support for furnaces purchased from elsewhere.
It is best to fill in our enquiry form, and mark that you require a furnace and we will automatically select and quote the best model for your application.
Later on this page we define the typical furnace we sell for use with ProboStat.
Temperature control and software
The furnace can be controlled manually from the front panel. It is possible to program the controller to perform steps and ramps. This, however is a bit cumbersome. A better way is to have software take care of it; entering the desired behavior is much easier than manual programming from controller front panel, and with software one can perform unlimited steps, and have a record of the furnace temperature as well.
There are two separate software that can do the furnace control. The first and the simpler one is called Omega Temp which allows user to easily program ramps and dwells from easy user interface. The second one is full out measurement, automation and data acquisition software, where furnace control is only a small part of the software, and is slightly confusingly called Omega. The latter (Omega) is more complicated and can be used to orchestrate complicated measurement setups with a range of various different instruments.

Low voltage furnaces
We can design and manufacture custom PID furnaces using direct current and low voltage < 40 VDC for special applications.

Heating mantle
We can deliver a custom tubular heating mantles suitable for temperatures more moderate than usually obtained with regular furnaces. A typical model is of ca. 30 cm length and covers temperatures from ambient up to 450 or 650°C. Power supply is by standard 110 or 220 V AC, regulated by an integrated type K thermocouple.
