    Heating Zone Length 440 mm ( single zone )
    Constant Temperature Zone 150  mm (+/-1°C)
    Temperature Controller
    MET certified 30 programmable segments for precise control of heating rate, cooling rate, and dwell time.
    Built-in PID Auto-Tune function with overheating & broken thermocouple broken protection.
    Over-temperature protection and alarm allow for operation without attendant(s).
    +/- 1 ºC temperature accuracy.
    RS485 Communications Port.
    The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at extra cost. 
    If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer laptop from us to avoid software installation problems.
    Vacuum Sealing & Connection CF type stainless steel flanges welded to two end of tube.
    KF-D40 vacuum port, KF-D25 gauge port, ball valves and one meter long SS pipe  are installed in one side flange for connecting to vacuum pump.
    1/4NFS adapter and SS needle valve are installed in another flange for gas flow.

    Warranty One year limited warranty for electrical and mechanical parts. (Consumable parts such as furnace liner, processing tubes 
    and o-rings are not covered by the warranty.
    Compliance CE Certified
    UL / MET / CSA Certification is available upon request, additional charges will apply       

    Tube furnaces with Stainless Steel tube are designed for using under vacuum and low pressure < 0.2 bar
    Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. 
     Vacuum pressures may only be safely used up to 1000°C
    The flow rate for gasses should be limited to< 200ml/min) for reducing thermal shocks to the tube
