  • One-year limited warranty with lifetime support.  (Consumable parts such as sample plates and heating elements are not covered by the warranty, please order the replacement at related products below.)
  • ATTENTION: Any damages caused by the use of corrosive and acidic gasses are not under the coverage of MTI One Year Limited Warranty.
  • CE Certified
  • The furnace is ready to pass TUV(UL61010) or CSA certification at an extra cost. 
Application Notes
Attention Notes
  • For preserving the longevity of the furnace components, we recommend the heating rate not to exceed 10 °C /min. The cooling rate shall also not exceed 10 °C /min.
  • This furnace lacks vacuum sealing, and toxic or explosive gasses are not recommended for use with this furnace without necessary safety controls and supervision.
  • Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating.
  • Performance degradation (i.e. furnace can not reach the maximum temperature of 1500°C or it is drawing a higher than normal working current) can be expected due to the use of aged SiC heating elements. It is necessary to replace all the heating elements.
