Tube furnace

A tube oven bụ ihe eletrik na-ekpo ọkụ nke a na-eji eme syntheses na purifications nke inorganic compounds na mgbe ụfọdụ na organic synthesis. Otu atụmatụ nwere ike ịnwe oghere cylindrical gbara gburugburu site na coils na-ekpo ọkụ nke a na-etinye na matrix na-ekpuchi okpomọkụ. Enwere ike ịchịkwa okpomọkụ site na nzaghachi sitere na thermocouple. Igwe ọkụ ndị ọzọ dị mgbagwoju anya nwere mpaghara okpomọkụ abụọ (ma ọ bụ karịa) bara uru maka nnwale njem. Ụfọdụ ndị na-achịkwa okpomọkụ dijitalụ na-enye interface RS-232, ma na-enye onye ọrụ ohere ịhazi akụkụ maka ojiji dị ka ramping, sucking, sintering, na ndị ọzọ.
