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: 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

For electrostatic experiments, for example, determination of the charge of a sphere and induction experiments. Hollow surface-treated brass sphere equipped with 4 mm holes for connecting banana connectors.

Supplier: PHYWE

Demonstration instrument for lossless measurement of DC and AC voltages. Due to the high insulation resistance (approx. 1014 ©), the instrument loads the voltage source insignificantly. At the same time, the voltage drop becomes negligible. The measuring systems are protected against disturbing fields and placed in plastic apparatus housings. The measurement can be studied from the back through a window. The large and clear scale and the design of the pointer make the instrument very easy to read even at longer distances. The scaling of the scale enables precision reading. Scale is also available on the back. The pointer is visible through a slit in the scale. Mechanical zero adjustment with thumbwheel. Protected against overload by flashing over spark gap. Connection with banana connectors to high voltage insulator and two sockets for ground connection on the top of the instrument. Used in electrostatic tests, often together with power supplies 765-1325 or eg for examination of the charge density on Faraday cages, conductors etc.

Supplier: PHYWE

Measurement insert for resistance measurement. Used together with demonstration instruments 765-1247. Clear, fine-grained scale with number markings. Measuring range window where the information automatically follows the measuring range switch. On the back there are measuring range switches, zero adjustment and contact sleeves for printers.

Supplier: PHYWE

A fog chamber from the well-known physics company PHYWE is the given focus of many exhibitions. Every day, thousands of visitors to technical museums, art museums, nuclear power plant information centers, universities and colleges are fascinated by these fog chambers that make the invisible background radiation visible. PHYWE has been developing and manufacturing these unique devices for more than 20 years. In total, there are more than 200 in operation in more than 40 countries. The fog chamber makes the invisible visible. Every second you can observe a large number of traces that originate from both cosmic radiation and the earth's natural radioactivity. The appearance of the trace immediately reveals the type of particle that has just passed. During normal operation, no additional preparation is used. If you want to increase the activity in the surface, you can blow in a thorium isotope.
