The device for measuring temperature, comprises a Peltier-tempering device (6) with a reception area (9) for a one-way reception container (5), and a thermistor holder (5) for the reception of the thermistor, where the heat transmission between the reception container and the tempering device is obtainable through heat radiation and heat conduction in intended use of the reception container. The heat conduction portion predominates and a contact between the tempering device and an external wall (11) of the reception container is adjusted to 1% of the surface of the external wall.

The heat conduction portion predominates and a contact between the tempering device and an external wall (11) of the reception container is adjusted to 1% of the surface of the external wall. The external wall turned to the reception container is spaced apart from the internal wall of the reception area. The reception area is fillable with a fluid under ambient pressure and the tempering device is regulatable in a temperature area. The regulatable tempering device is regulatable at 1-20[deg] C. The thermistor holder and/or a temperature reception is active thermostattable. An interval between the internal wall of the reception area and the external wall of the reception container is adjustable in intended use. The external wall of the reception container comprises a rib-like structure. The thermistor holder comprises a heat conduction area with a first heat conduction and a heat insulation area with a second heat conduction, where the first heat conduction is greater than the second heat conduction.
