Performance data:

Temperature range without air conditioning: +20...+100 °C

Temperature stability without air conditioning: +0.2 ... t0.5 K (over time) depending on the range, in steady state

Temperature range with air conditioning: 20...+95 °C

Temperature stability with air conditioning: +0.2 ... +0.5 K (over time) depending on the range, in steady state

Dew point range: 20...+94 °C

Humidity range: 10...98 % RH

Humidity stability: +3 ... +5 % RH depending on the range, in steady state

Temperature change rate measured in the exhaust without a 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 specifications refer to an ambient temperature of max. +25 °C and the specified nominal voltage.
For proper operation of the system, the ambient temperature must be between +10 and +35 °C.
