Tube holder made of robust plastic for holding D-series electron tubes. Stand has a wishbone, 360deg rotating clamp made of heat-resistant plastic. On rubber feet to prevent slipping. Dimensions: approx. 230x175x320 mm3 Weight: approx. 1.5 kg
Digital Counter For event counting, a fixed counting period can be programmed in a range from 0.1 ms to 99999 s. Counter events (e.g. start or stop) can either be triggered by a signal to the input sockets or manually via switches. The unit includes a plug-in power supply.
Tube holder to support all S series (student) electron tubes for easy and safe operation. The five pin sockets for the tube are concealed inside the tube holder. A cathode protection switch is integrated into the tube holder, to protect the heated cathode from excessive voltage.
Universally applicable, floating, high-voltage power supply with built-in, high voltage resistant transformer to supply the heater voltage for electron tubes. Continuously adjustable high voltage, safe to touch, with passive current limitation and analogue voltage display.
