Supplier: 3B Scientific

Vane wheel device is used for demonstrating air and heat flows generated by a burning candle, water vapour or other heat sources. Made of Aluminium and mountable on a long needle.

Supplier: MOLLER THERM

Milk glass scale on polished wooden board. Colored liquid filling. Measuring range -10 to +100 ° C, 0 to +80 ° R, +20 to +212 ° F.

Supplier: PHYWE

For demonstration of the function of an electric compression heat pump.

Supplier: CORNELSEN EXPERIMENTA

For experiments with absorption of heat radiation. Consists of a black and a white E-flask and two thermometers (0 to 50 °C).

Supplier: 3B Scientific

Evacuated glass flask containing i.a. electron gun with directly heated tungsten wire cathode and a cylindrical, collimating anode. The generated beam is allowed to stroke along a semi-transparent mica disc in the center of the tube. Luminescent coating on the front of the disc makes the beam appear. Two of the edges of the back are provided with graduated scales.

Supplier: MOLLER THERM

Radiometer according to Crookés. Consists of a glass container on foot with low air pressure and needle-bearing spinner with four vertical mica discs. The discs are black on one side and shiny on the other. The discs thus absorb radiation differently. The higher temperature of the dark side means that the air molecules get greater kinetic energy in collision with the dark side of the discs than with their shiny side. The result is that the spinner starts to rotate.

Supplier: CORNELSEN EXPERIMENTA

Model of a hot air balloon. Made of heat-resistant plastic foil. Equipped with metal-reinforced opening.

Supplier: CORNELSEN EXPERIMENTA

Apparatus for examining the conversion from electrical energy to light and heat energy. Consists of a plastic container, lid with light bulb (6 V / 5 A) in base and a resistor. The container is filled with water and the temperature change is measured. Equipped with connections for 4 mm banana plug.

Supplier: CORNELSEN EXPERIMENTA

Circular gutter made of aluminum sheet with insulating handle. Fits U-core 765-1077 and was used, among other things, when demonstrating the principle of induction furnaces.

Supplier: CORNELSEN EXPERIMENTA

72 series-connected semiconductor elements, mounted between two ceramic plates which in turn are attached to heat-conducting metal. If the metals are exposed to different temperatures, a voltage arises, sufficient to drive, for example, a slightly rotating motor. The thermogenerator can also be run in the other direction, ie. a voltage is connected and a temperature difference is obtained across the metal legs.

Supplier: GR NNA PLASTEMBALLAGE AB

An alloy with an approximate composition of 48% by weight bismuth, 28% lead, 12% cadmium and 12% tin. The metal has an unusually low melting point (+65 ° C) and is used in the study of phase transformations, melting point determinations, etc.

Supplier: PHYWE

Used to detect thermal radiation, visible light and ultraviolet light. The sensitivity is wavelength dependent in the range 150 nm-15 µm. The output voltage is closely proportional to the incident radiant energy. Suitable for measuring small temperature differences. Quick stabilization, 2-3 p. Consists of 16 series-connected thermocouples placed in a conical reflector. The elements are protected by a high-gloss metal cylinder, which is fitted with a removable protective glass at the front. Suitable for use with, for example, microvolt amplifiers 765-1293 in conjunction with demonstration instruments 765-1247 or for connection to Phywe's large analog or digital demonstration multimeters. Comes with protective tube and gap.
