Internal report memory 1024kB for storing actual temperature, setpoint temperature and error
states with time stamp
•
Fan with speed adjustment on recirculation ovens (adjustment in 10% steps)
•
Manually adjustable air valve for recirculation or fresh air operation
•
Integral weekly programmer with group function (e.g. all workdays)

•
Convenient 3-point temperature calibration
•
Temperature-dependent ventilation of control panel and door
•
Serial RS232C interface for computer-supported temperature programmes and for reading
the internal report memory
•
MEMMERT software “Celsius 2005“ for remote operation of oven via a PC
•
Special equipment (to be ordered separately as accessories): adjustable temperature limiter (TWB),
subframe, wall bracket, wire shelf, sterilisation cassette, cable RS232C to DIN 12 900-1
3.2 Material quality
For external casing and working chamber MEMERT are using stainless steel (Mat.Ref. 1.4301) which features
high strength, optimum hygienic properties and corrosion resistance against many (not all) chemicals
(warning against e.g. chlorine compounds).
The oven load has to be checked carefully for its chemical compatibility with the above materials.
A compatibility table covering all these materials can be requested from MEMMERT.
