Industrial & Laboratory Constant Temperature Ovens DNE401/411/601/611/811/911



Available Various Functions
  • Incorporates with maximum 99 steps, 99 patterns program controller with repeat function.
  • Loaded with Total Operation Hours Timer
  • Data acquisition from internal test device is easy because of cable holes
High-performance, energy-saving, programmble constant temperature, forced convection ovens.
Due to high precision control system, high performance temperature control is realized, and the CO2 discharge, power discharge also displayed at the monitor.
The DNE series represents forced convection constant temperature oven. They achieve an energy-saving rate of 30 to 40% compared to previous models.
