Features:

Closed water cooling system with proximity sensors control the flow and temperature of cooling water lines
Software enables programs to form heating-cooling, each of which comprises a sequence of independent segments, defined by three parameters: the increment of the voltage on the segment length of a segment of time and limit the voltage on the segment. It is possible to maintain these programs in the electronic memory of industrial computer. The software implemented the ability to "hot" switch from one program to another.
Control and monitoring provides a fully controlled by the user on the software and hardware levels of crystal growth process
Implemented the ability to control mechanical parts installation, implemented the ability programming parameters of the heater power
Furnace is equipped with preinstalled software on a perpetual commercial license
"hot" switch between automatic and manual types of control, at any moment you can stop the execution of the current program is automatically carried out the process and manually setting the new parameter set to continue process in automatic mode

1200â?? tube furnace uses high-quality electric furnace wire as heating element, the maximum heating temperature is 1200â??, and the diameter of the quartz furnace tube is 50mm. If the customer needs, can contact the technician to customize the larger diameter furnace tube. The default heating zone is single temperature zone. It can also be customized according to customer needs. The temperature zone is controlled by the precision temperature control meter for PID temperature control. The 30-segment temperature rise and fall program can be edited, and the overheating and open circuit of thermocouple protection functions are also available. The flanges on both sides of the furnace tube are equipped with a digital vacuum gauge and a mechanical pressure gauge, which can be used to control the atmosphere in the furnace tube. At the same time, the tube furnace is operated by HD true color touch screen, which is easy to use. Even non-professionals can master the use of the instrument after simple training, which can greatly improve your experiment efficiency.
