Minimum temperature -72 °C, discontinuously2)
Temperature change rate
cooling according to IEC 60068-3-53) approx. 3,0 K/min., on average, measured in the air inlet
Temperature change rate
heating according to IEC 60068-3-53) approx. 4,0 K/min., on average, measured in the air inlet
Temperature change rate
linear between +85 °C to -40 °C approx. 1,0 K/min., measured in the air inlet
Temperature deviation, in time, in steady state, depending on the temperature ±0,1 K to ±0,5 K
Temperature homogeneity, in space, depending on the adjusted set point value³ ±0,5 K to ±1,5 K
Max. heat compensation 1500 W
Calibration values +23 °C and +80 °C
2) In case of continuous, long-term operation below +5 °C ice might form on the evaporator if outer humidity is allowed to enter the chamber, for instance, by open apertures, doors or if additional humidity is generated by specimens or others.
In these cases, the evaporator needs to be defrosted from time to time by heating up to +10 °C.
³) In the temperature range of minimum temperature to +150°C.
