Temperature controller 

40 programmable segments (Shimaden fp93 made in Japan), 

It can separate into 4,2,1 programs, ie. 4x10 segments.

FP93 have 6 PID controls, different PID are used for low,middle,

high temperature for precise control.

Over-temperature and over-current protection, shutdown automatically when thermocouple is broken

( it will shut down power when temperature is higher than 1620⁰or thermocouples is broken, 

"ON" on the board is off and "OFF" is on)

There is Fahrenheit (F) and Celsius (C) for option.

With 485 communication interface: which can stop the furnace automatically.

Safe protection system

The furnace door is equipped with a travel switch, and when the furnace door is lowered, the power supply will be automatically cut off to prevent the electric shock from touching the heating element.

Air switch

 The furnace is equipped with air switch, and when the current exceeds the rated current of the air, the empty meeting automatically jumps open and effectively protects the furnace

Certificate

CE

Position limit switch

When the lifting rod is at its highest or lowest point, the position limit switch will automatically cut off the lift bar, so that it will not rise or fall
