Müller Geiger counter Tube Landistgyr
Swiss: The Muller Geiger counter tube is an
evacuated tube, which contains an internal
electrode that, upon the impact of a radioactive
particle, releases an impulse (current or
voltage pulse unk.). Serves for the
detection of radioactivity |
Cerberus Männedorf Swiss S90 140 Voltage
Stabilizer: These tubes stabilize 90 Volts. The
Swiss tubes were well known for their precision.

Cerberus Männedorf Swiss GR16: Cold
Cathode Tubes were the world specialty of two
Swiss Companies. There are gas filled tubes
(Diodes) with an ignition electrode. Thyratrons.
If a minimal voltage is applied to the ignition
electrode (nanoA) then the tube ignites (the
gas inside ionizes) allowing more current
to flow. The ignition condition is indicated by
glowing neon gas. The life span of the Tube is
about 25,000 hours. |
