With a special addition, the analogue instrument can be turned into a digital instrument with simultaneous analogue display. In order to extend the measurement possibilities, there are also measurements for power and voltage amplification. The replaceable measuring areas are slid into a slot on the top of the instrument ('toaster principle').

Educational Materials, Electricity/Magnetism, Application: Physics, Adapter, BNC connector to 4 mm Jack plugs with 19 mm spacing.

Supplier: PHYWE

For demonstration of electric fields between electrodes of different shapes. The electrodes have been applied in thin conductive layers on plexiglass plates and the field line images appear in groats placed in a cuvette with 1 to 2 mm castor oil (the cuvette is placed on the plexiglass plate). The cuvette has an annular electrode in the outer jacket and a 4 mm connection sleeve. The cleaning is easy when electrodes resp. plexiglass plate never comes into contact with the oil. Suitable voltage source: High voltage generator 0 to 25 kV or Van de Graff generator.

Supplier: 3B Scientific

Highly evacuated electron tube for determining the wavelength of electrons as a function of the anode voltage from the radii of the diffraction rings and the distance between the lattice planes of graphite (Debye-Scherrer-diffraction) and rendered visible on a fluorescent screen. Also intended for determining the wavelengths of monochromatic radiation at different anode voltages from the radii of the diffraction rings and the lattice plane spacing of graphite, as well as confirming de Broglie’s hypothesis.

Supplier: CORNELSEN EXPERIMENTA

Bare wire in a roll, on a plastic former.

Supplier: CORNELSEN EXPERIMENTA

Shows that the bottom pressure in a liquid depends only on the height and not the shape of the container. The fluid pressure is transferred via a rubber diaphragm to an adjustable hand. Comes with four containers of different shapes. Dimensions.

Supplier: GR NNA PLASTEMBALLAGE AB

Trolley, 100 g, of lacquered sheet metal with nylon wheels. Equipped with hook and hole for mounting weights.

Supplier: CORNELSEN EXPERIMENTA

Intended for use on overhead projectors for demonstration of function and principle for different types of motors. Made of strong, transparent plastic. Equipped with suction feet.

Supplier: CORNELSEN EXPERIMENTA

Bicycle dynamo with transparent housing. Consists of magnetic anchor and coil mounted on base with belt drive. Equipped with connections for 4 mm banana plug and light bulb 3.5 V/0.2 A.

Supplier: GR NNA PLASTEMBALLAGE AB

Ribbons with elderflower balls suspended in thin threads. Placed around the head of a person who stands on an insulating surface and can be charged with the help of a belt generator. The balls stand out correctly. The belt can also be placed directly on the belt of the belt generator.

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.

Supplier: PHYWE

Ice cream sphere filled with noble gas of low pressure. The tube's two cylindrical necks are protected by plastic sleeves and are designed to fit in Helmholtz coils 765-1207. The tube is used to show how an electron beam is deflected in a magnetic field. If the tube is in a homogeneous magnetic field with sufficient strength, the electron beam becomes circular. The tube is equipped with an internal measuring scale with fluorescent markings at distances of 4, 6, 8 and 10 cm (2r) from the cathode. The tube is well suited for determining the charge-mass ratio of the electron with great accuracy.

Supplier: GR NNA PLASTEMBALLAGE AB

Used to show the effect of air resistance in free fall. An air pump or water suction is used to evacuate the air in the pipe. Supplied with: 1 glass tube, 2 rubber plugs, one of which with a crane tube. 3 test specimens of resp. down, plastic and lead.

Supplier: PHYWE

Same as 765-1149 but without painting. 50 components incl. Manual.

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).
