    1.1.1     Performance Data for Temperature Tests

     

    Maximum temperature

    +180 °C

     

     

    Minimum temperature

    -72 °C, discontinuously 2)

     

     

    Cooling-down rate as per
    IEC 60068-3-5

    approx. 6,7 K/min., on average, measured in the air inlet

     

     

    Cooling-down rate
    between 85 ... -40° C

    approx. 5,2 K/min., on average, measured in the air inlet

     

     

    Heating-up rate as per
    IEC 60068-3-5

    approx. 6,8 K/min., on average, measured in the air inlet

     

     

    Heating-up rate
    between -40 °C … +85 °C

    approx. 7,3 K/min., on average, 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 ±2,0 K

     

     

    Heat compensation     at -20 °C
                                         at +20 °C

    3000 W
    3000 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 has to be defrosted from time to time by heating-up to 3+10 °C.

     

     

    3)  In the temperature range of minimum temperature to +150°C.
