1. Temperature failure of  high temperature vacuum furnace:XvpMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

Causes: (1) The thermocouple wire is disconnected or contaminated (2) The temperature control instrument is faulty (3) The thermocouple compensation wire is connected reversely or short-circuitedXvpMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

Remedy: (1) Replace the thermocouple (2) Repair according to the instrument manual (3) Reconnect or eliminateXvpMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
