The invention is related to a liquid nitrogen and liquid helium flow measurement chamber with optical window, developed in order to carry out measurements at low and high temperatures, compatible with measurement systems such as optical, magneto-optical, magneto-transport, microwave and magneto-caloric effect. The system enables to carry out measurements at high temperatures by means of the heater (6) that has been placed inside the nonmagnetic stainless steel holder (7) and besides this, it also enables to carry out measurements at low temperatures using liquid nitrogen and liquid helium by means of the liquid nitrogen and liquid helium transfer pipes (5). The system can be vacuumed up to ~10"6 mbar values by means of the vacuum connection pipe (14) and the vacuum cover (4) with optical window, during low temperature measurements. All of the connections that are used from the sample measurement location (8) to the contact connection station (9) for transport measurements, are controlled by means of a 19 pin connector (11).
