DKN-900 is equipped with a state-of-the art HiTEC® IV CR Type microprocessor PID temperature controller with up to 16 segment/32 step programs. Including auto start, auto stop, ramp and soak modes, which can be easily inputted through the keypad control.

 

 

  • The self-diagnostic function alerts users both visually and audibly if the temperature sensor, triac or heater malfunctions. At that time, the heater circuit will automatically turn off.
  • All models have a Type 304 (18-8) Stainless Steel interior, as well as a cold rolled carbon steel exterior finished with baked melamine for durability and appearance. Stains from splashes, fumes or chemicals can be simply wiped clean with alcohol. Maximum performance is backed by our 24 month limited warranty policy.
  • An optional 1 inch cable port is available for data acquisition. (DKN-900 - a cable port is equipped as standard.)
  • CSA approvable
