connection to the PC RS232C interface, 25-way printer cable (parallel, screened)
4.2 Material quality
For external housing MEMMERT employs stainless steel (Mat.Ref. 1.4016). The chamber is made from
stainless steel (Mat.Ref. 1.4301) which exhibits high stability, optimum hgygienic 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.
