One year warranty, lifetime technical support
Special tips: 1. Consumable parts such as heating elements, furnace tubes, sample crucibles, etc. are not under warranty.
2. Damage caused by the use of corrosive gases and acid gases is not covered by the warranty.
1. The air pressure in the furnace tube cannot be higher than 0.02MPa
2. Due to the high internal pressure of the gas cylinder, when introducing gas into the furnace tube, a pressure reducing valve must be installed on the gas cylinder. In order to ensure safety, it is recommended to use a pressure lower than 0.02 MPa.
3. When the furnace tube used is corundum tube, when the furnace temperature is higher than 1500 ℃, the furnace tube cannot be in a vacuum state, and the pressure in the furnace tube must be equal to the atmospheric pressure.
4. The gas flow entering the furnace tube needs to be less than 200SCCM to avoid the impact of the cold air flow on the hot furnace tube
5. For the experiment of sample heating, it is not recommended to close the suction valve and inlet valve of the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you must always pay attention to the indication of the pressure gauge. If the pressure is greater than 0.02MPa, you must immediately open the exhaust valve to prevent accidents (such as furnace tube rupture, flange flying out, etc.)
6. Don't use graphite crucibles in alumina tubes
7. MoSi 2 heating element must not be used at low temperature (400 ℃ -700 ℃) for a long time, otherwise the heating element may be damaged
(1) The thickness D1 of the hot end of the silicon molybdenum rod is 7mm, 6MM adopted by general manufacturers, the heating end is thick, not easy to bend, the surface load of the rod is low, and the service life is long.
(2) Using hot bending technology, uniform resistance and long service life
(3) Lu cold end length is 210mm, 400X300X300 furnace is 260, general manufacturers use 180mm, cold end long furnace top temperature is low.
(4) The oxidized amorphous film on the surface of the silicon molybdenum rod is dense, which can better protect the silicon molybdenum rod.
2. Installed air switch and leakage protector:
When the circuit is over-current or leakage, the meeting will be disconnected automatically.
3.Can connect with computer
The furnace is equipped with a communication interface and software, which can directly control various parameters of the furnace through a computer, and can observe the PV and SV temperature values on the furnace and the operation of the instrument from the computer. The actual heating curve of the furnace will be drawn by the computer in real time And can save the temperature data at each moment, you can call up at any time

Soft-Start Current-Limit Trigger Non-Current-Limit Used by Most Manufacturers
Xiamen Bote Trigger
1. Phase-shift triggering (with soft start and current limit functions)
2. Current limiting function: No matter how you set the heating rate, the secondary current of our electric furnace is always limited to 170A, which effectively protects the equipment. Due to the current limiting function, the furnace door can be opened at high temperatures. If the electric furnace you use needs to limit the heating rate of the furnace during the heating process (for example: it is not allowed to exceed 3 ° C / min after 1400 ° C, etc.), a non-current-limiting trigger is used. If the heating rate is set incorrectly or the heating rate is too fast, the current will be very large and the device will trip or burn out.
3. Soft-start function: The current will increase gradually when starting up, and the impact on the heating element is small, which is beneficial to the extension of the heating element life.
4, protection function: If the current exceeds the limit current, the trigger will automatically cut off the trigger function to cut off the current to protect the electric furnace.
7.UL certified transformer

2.Small transformer sound
3. Low temperature of transformer
