Note: Chambers with voltage and frequency changer: Average heating up time reduced by 0.3 K/min
each.
All technical data is specified for unloaded chambers with standard equipment at an ambient temperature
of +22 °C +/- 3 °C / 71.6 °F +/- 5.4 °F and a power supply voltage fluctuation of +/-10%. Technical data is
determined in accordance to BINDER Factory Standard Part 2:2015 and DIN 12880:2007.
All indications are average values, typical for chambers produced in series. We reserve the right
to change technical specifications at any time.
If the chamber is fully loaded, the specified heating up and cooling down times may vary ac-
cording to the load.
Bringing a source of humidity into the inner chamber will affect the minimum humidity specifi-
cation and may affect the humidity accuracy.
