Operating & Constructional Features

  • Microprocess PID control / Auto-tuning / Calibration.
  • Chamber supports three different languages:
    English, Chinese, and Korean.
  • CPU logic control system.
    - Optimum control of temperature / humidity with economical power consumption.
  • Touch Screen Type Display.
    - 5.7-inch Color LCD display with interactive input system. (only floor type)
    - Easily visible set value: set point (SP) / present value (PV) are also added on the colorful LED controller.
    - Temperature & humidity, timer settings, and operation conditions.
    - Temperature, humidity, and other operating parameters can be recorded using a chart recorder.
  • Programming operation. 
    Description TH-CR-270
    Programmable Pattern Capacity 120
    Pattern Repeat Time 999
    Max. Segments per a Pattern 100
    Available Max. Segments* 1200
    Programmable Process Time per a Segment 0 to 99 hr 59 min
    * Even though the max. segments per a pattern are 100, available total segments are up to 1200 not 12000, so you need to arrange the number of segment and patterns properly.
