Chamber for tensile tester
Self-supported two-fold body frame.
Made if stainless steel 2 mm 1.4301.
Melted, polished and brushed from the outside.

Heating power 2.3 kW (220 volt).
Range of temperature -80 deg. C to 280 deg. C (optional 350 deg. C)
Air circulation with a centric blower.

Front door contains of 4 glass-platens:
between inner glassplatens are heating coils to remove frosting of the glass.

Up and downhole has a teflon guide tube outside, V2a inside.
Insert shells can be added to reduce to a smaller diameter for the pullrods.

Heat up speed 15 deg C/min (from 20 to 80 deg. C without grip).

Cooling reguires liquid nitrogen, which is controlled by a magnet valve on backside of the chamber.

Temperature frostings of the internal glass can occure when opening the door and can be solved by using heating coils.
To come down to -80 deg C 4 kg liquid air is needed. To keep -80 deg C 0.5 kg liquid air per hour is needed.
