Three Zone Precision Temperature Control System (SCR ) with 30 Segments Programmable (9 KW) for DIY Furnace upto 1500C - EQ-MTC-Z3

0.0/5 rating (0 votes)



  • EQ-MTC-Z3 temperature control unit is designed for precision control three zone tube furnace from 100 - 1500 oC with heating elements of resistant wire or SiC.
  • Just connecting power cord and thermo-couple with the unit, you can run your furnace automatically.
  • The unit is installed in a heavy duty steel case with precision digital temperature controller and voltage & current meters.
  • The controller uses PID automatic control via  SSR and  provides more accurate temperature control within +/1oC
  • Built in "auto tune" function allows you to adjust furnace temperature with minimum over-shooting.
  • Threedigital temperature controller d each has built in and  each controller has 30 segments programmable indenpendently
  • Built in cooling fan inside case avoid temperature effect on the controller.
