Specific Introduction:
KJ-1200X-III-C is an open-type three-zone tube furnace with a heating zone of 450mm (150+150+150mm). The diameter of the quartz furnace tube is 25, 50, 60, 80 or 100mm. The three temperature zones are controlled by an independent temperature control system, which can set 30 steps of temperature rise and fall programs, the temperature control accuracy is +/- 1℃, and the maximum temperature can reach 1200℃.

Warranty	One year warranty and lifetime technical support. Special tips: 1. Consumable parts such as heating elements, quartz tubes, sample crucibles, etc. are not included. 2. Damage caused by the use of corrosive gas and acid gas is not covered by the warranty.
Vacuum system	·It can reach 50mTorr by mechanical pump ·It can reach 10E-5 Torr through molecular pump ·A cold vacuum trap can be purchased to avoid pollution caused by the vacuum pump
Quality Certification	CE certification.
Precautions for use	·The air pressure in the furnace tube cannot be higher than 0.02MPa ·Because the internal pressure of the gas cylinder is high, a pressure reducing valve must be installed on the gas cylinder when gas is introduced into the furnace tube. To ensure safety, it is recommended to use a pressure lower than 0.02MPa. It is recommended to purchase a pressure reducing valve from our company. The company's pressure reducing valve has a range of 0.01MPa-0.1MPa, which will be more accurate and safe when used ·When the furnace body temperature is higher than 1000℃, the furnace tube must not be in a vacuum state, and the air pressure in the furnace tube must be equal to atmospheric pressure ·The gas flow into the furnace tube must be less than 200SCCM to avoid the impact of the cold atmosphere on the heated quartz tube ·Long-term use temperature of quartz tube <1100℃ ·For the sample heating experiment, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you should always pay attention to the indication of the pressure gauge. If the indication of the air pressure is greater than 0.02MPa, you must open the vent valve immediately to prevent accidents (such as furnace tube rupture, flange flying, etc.)
