*1 Performance data above based on 23 ±5 °C room temperature, 65%RH ±20% humidity, and no process load.
Temperature control accuracy, temperature fluctuation, temperature distribution accuracy, and temperature gradient are the values measured using Toshiba Silicone TSF485-50.
Performance varies depending on the environmental temperature, type of medium (water, silicone oil) used, and operating temperature.
