  • The perfect machine to be used for every kind of testing and inspection on electrical component production lines, analysis inspection, temperature characterization, food-related storage confirmation, etc.
  • Internal operation is possible as the door is opened and closed under high and low temperature conditions.
  • Employing a motorized sliding front glass door, there is little temperature fluctuation when the door is opened and closed, and it's possible to view internal operations.

  1. Capacity is when doors are fully closed.
  2. Temperature range is when under no load, no test sample present, operating at the rated voltage, temperature is where air is being blown out inside the chamber, at an ambient temperature of +10 °C to +25 °C.
  3. The temperature and humidity divergence values are based on the JTM standard of an ambient temperature of +10 °C to +25 °C, when under no load, when there is no test sample present, under stable conditions. (The value is the average of the absolute value of the averages of the positive and negative values of 8 corner points and the center of the sample chamber.)
  4. The temperature rise and fall times are when the ambient temperature is +20 °C, with no load, when there is no test sample present, at the rated voltage, tested at the air outlet point inside the chamber when operating under maximum capacity.
  5. Does not include protruding parts.
  • There may be a 2 °C to 7 °C difference between the temperature inside the chamber and the temperature of air being blown into chamber due to intake of external heat.
