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.

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.
