Temperature
Temperature recording by means of Pt100 in a 4-wire circuit
Adjustment range: Normal mode: 20 °C to 50 °C
Sterilisation mode: 160 °C (4 hours) via STERICard
Adjustment precision: 0.1 °C
Control range: from 8 °C above room temperature to 50 °C
Variation (time): max. ±0,1 °C at 37 °C
Variation (spatial): max. ±0.3 °C at 37 °C
Humidity
The relative humidity in the chamber is measured by a capac-
itive humidity sensor and displayed digitally in percent.
The measurement precision of the humidity sensor is 1 % rh
►
Adjustment range: 88 to 97 % rh (for models with
humidity module 40 to 97 % rh)
►
Adjustment precision: 1 % rh
►
Display range: 10 to 98 % rh
►
Variation (time): max. ±1 % rh
CO
2
The CO
2
content is determined through an NDIR measur-
ing system, controlled constantly by a microprocessor and
displayed digitally in percent
►
Adjustment range: 0 to 10 % (for models with CO
2
or
premium modules 0 to 20 %)
►
Adjustment precision: 0.1 %
►
Variation (time): max. ±0.1 % rh
►
Variation (spatial): max. ±0.3 %
O
2
(only if equipped with O
2
module)
The O
2
content is determined with a long-lasting, mainte-
nance-free zirconium dioxide sensor, constantly controlled by
a microprocessor and displayed digitally in percent
►
Adjustment range: 1 to 20 %
►
Adjustment precision: 0.1 %
►
Variation (time): max. ±0.1 %
