Temperature
Set temperature range: -10 to +60 °C

Operating temperature range:
from -10°C to +60°C without humidity
(not suitable for long-term storage at sub-zero temperatures. During continuous operation, glass doors may frost over)

Operating temperature range:
from +10°C to +60°C with humidity and/or light

Temperature setting accuracy: 0.1 °C

Temperature sensors:
2 Pt100 sensors, DIN A class, 4-wire configuration, mutually monitoring and taking over in case of failure

Humidity
Humidity supply:
Distilled water supply from external tank via self-priming pump

Humidification:
Steam generator-based humidification

Humidity:
Active humidification and dehumidification adjustable within the 10–80% rh range with digital relative humidity display – display resolution 0.1%, setpoint accuracy 0.5%

Control Technology
ControlCOCKPIT
TwinDISPLAY. Adaptive, multifunctional digital PID microprocessor controller with two high-resolution TFT color displays.

Adjustable parameters:
temperature (°C or °F), fan speed, relative humidity, program time, time zones, summer/winter time

Language settings:
German, English, Spanish, French, Polish, Czech, Hungarian, Italian, Chinese

Timer:
Digital countdown timer with target time setting, adjustable from 1 minute to 99 days

SetpointWAIT function:

Itjdpfx Adexcgh Reqsr
Calibration:
Up to three user-defined values for temperature/humidity and two for CO₂

Ventilation
Fan:
Forced air circulation in the working chamber, adjustable from 10–100% in 10% increments

Communication
Documentation:
Program retained in memory in case of power failure

Programming:
AtmoCONTROL software on USB stick for programming, managing, and transferring programs via Ethernet interface or USB port

Safety
Temperature control:
Mechanical temperature limiter TB, protection class 1 in accordance with DIN 12880, which disconnects heating approx. 10 °C above setpoint temperature

Temperature monitoring:
Over- and under-temperature monitor TWW, safety class 3.3, or adjustable temperature limiter TWB, safety class 2, selectable from display

AutoSAFETY:
Integrated over- and under-temperature protection system "ASF", automatically tracks set value within fixed tolerance range, alarm if temperature is exceeded or falls below threshold; in case of over-temperature, heating is shut off, in under-temperature – compressor

Self-diagnostic system:
Integrated fault diagnosis for temperature and humidity monitoring

Alarm:
Visual and acoustic

Heating concept
Air jacket:
Air jacket heating system for gentle, even heating

Heating concept:
No sample drying caused by the cooling unit due to separation of heating jacket from chamber interior

Cooling:
Energy-efficient, CFC-free heating/cooling system, refrigerant R 134A

Defrosting:
High-efficiency, automatic defrost system

Standard equipment
Factory calibration certificate
Standard values: +10°C and +37°C, 60% rh at +30°C
