    Specific Introduction:
        KJ-1500X-II is a dual temperature zone open type tube furnace. The two temperature zones are controlled by two independent temperature control systems. Each temperature zone can be set with 30 sections of temperature rise and fall programs, and it has a couple of breaks. With overheating protection, the temperature control accuracy is up to +/- 1°C, and the maximum temperature of the instrument can reach 1500°C. This high-temperature tube furnace is particularly suitable for annealing and sintering samples in an atmosphere protection or vacuum environment.

    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 ·The mechanical pump can reach 50mTorr (reference value)
    ·It can reach 10E-5 Torr through molecular pump (reference value)
    ·A cold vacuum trap can be purchased to avoid pollution caused by the vacuum pump
    Quality Certification All electrical components (>24V) have passed UL/MET/CSA/CE certification. If the customer pays the certification fee, the company guarantees that a single device has passed the German TUV certification or CAS certification.
    Precautions for use · Pipe plugs should be added on both sides of the equipment to ensure the sealing of the constant temperature zone and flange.
    · Please use the program to cool down when cooling down. It is not recommended to directly press the "STOP" button to cool down. Do not turn off the power of the device before the device temperature drops to room temperature to prevent safety problems
    ·The air pressure in the furnace tube cannot be higher than 0.02MPa
    Do not use graphite crucible in alumina tube
    ·Because the internal pressure of the gas cylinder is relatively high, a pressure reducing valve must be installed on the gas cylinder when the gas is fed into the furnace tube. It is recommended to purchase a pressure reducing valve from our company. The range of our company's pressure reducing valve is 0.01MPa-0.1MPa. It will be more precise and safe to use
    ·Can not maintain negative pressure operation at 1400℃ high temperature
    ·The gas flow into the furnace tube must be less than 200SCCM to avoid the impact of the cold atmosphere on the heated corundum tube. The long-term use temperature of the corundum tube is <1750℃
    ·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.)
