Ramp programming for temperature and humidity, active humidity control, and the precise temperature regulation provide for a controlled, physiologically ideal environment for the simulation of real conditions. Suitable for a wide range of applications from building physics over corrosion tests to biological research.

Standard scope of delivery

Venting and control systems:

• homogenous atmosphere and temperature distribution in the interior by means of encapsulated and turbulence-free ventilation system
• adaptive, fuzzy-supported, multi-functional and digital PID micro-processor control
• self-diagnostics system to find errors for temperature and humidity control
• 2 Pt100-sensor DIN-class A in 4-conductor measurement with changing monitoring and function adaption at exactly the same temperature
• digital real-time week programme-clock with day group functions, can be set by the minute
• relative-time countdown clock for tempering profiles with up to 40 ramps, each segment can be set from 1 min to 999 hrs
• digital display of all temperature, weekday, time, humidity and set-up default values - language selection via set-up
• digital target value specifications (resolution 0.1°C to 99.9°C, 0.5°C from 100°C) and display of current value (resolution 0.1°C) of temperature values (LED)
• active humidification and dehumidification (20-95% rh) with digital display of relative humidity display resolution 0.5%, setting accuracy 1%
• humidification with distilled water from external container by means of self-suction pump
• integrated GLP-conform long-term logging (ring buffer) of all relevant data as data logging - 1024 kB
• saving the programme run in case of power failure
• parallel printer interface (incl. real-time clock with date function) for all PCL3-compatible ink jet printers for GLP-conform documentation
• USB-interface incl. Memmert programming and logging software "Celsius" with advanced features
• chip-card control incl. 1 MEMoryCard XL with 32 kB memory (max. 40 ramps)
• 2nd chip-card (STERICard) for interior sterilisation with fixed values (4 hrs/160°C) without removing sensors

Heating concept:

• large-sized multi-function allround heating with additional door and backwall heating to avoid condensate formation
• incl. factory calibration certificate at +60°C

Multiple overheating protection:

• with acoustic and optical alarm in case of excess or insufficient temperature and rh, warning when door is open and water container is empty
• separate, electronic temperature selection guard TWW, protection class 3.1, can be set digitally
• additional integrated monitoring of excess or insufficient temperature "ASF", which automatically follows the target value in freely selectable distance
• mechanic temperature limit TB protection class 1 to turn off heating at ca. 10°C above max. chamber temperature

Structure stainless-steel housing:

• fully insulated stainless-steel door with double lock and 4-point adjustment
• inner glass door
• fully galvanised stainless-steel back wall

Interior:

• easy-to-handle stainless-steel workspace enforced with deep-drawing ribbing W.-St. 1.4301 (ASTM 304), hermetically welded, electropolished
• 2 shelves made of stainless steel, perforated

Temperature range:

• with humidity: from +20°C (but min. 8°C above room temperature) to +90°C
• without humidity: von +20°C (but min. 8°C above room temperature) to +160°C
• temperature deviation at 50°C: < ±0.3°C

Power / Power input:

• 230 V (±10%), 50/60 Hz

External dimensions: Depth without door handle, depth of door handle 38 mm.
Inner dimensions: Depth is reduced by 25 mm for the fan.

Special versions like ducts in the rear wall, additional Pt100s etc. are available on request.
