Performance data:
Temperature range without climate control: +20...+100 °C
Temperature stability without climate control: +0.2 … ±0.5 K (time-dependent) depending on the range, in the stable state
Temperature range with climate control: 20...+95 °C
Temperature stability with climate control: +0.2 … +0.5 K (time-dependent) depending on the range, in the stable state
Dew point range: 20...+94 °C
Humidity range: 10...98 % RH
Humidity stability: +3 ... +5 % RH, depending on the range, in the stable state
Temperature change rate measured in the outlet without test specimen and without load
- Cooling: 0.5 K/min on average, between +100 and +20 °C
- Heating: 0.5 K/min on average, between +20 and +100 °C
The performance data refer to an ambient temperature of max. +25 °C and the specified rated voltage.
For proper operation of the system, the ambient temperature must be between +10 and +35 °C.
