decatron
OG-9 is a counting decatron with a directional cathode for operation in
calculating and calculating-solving devices and for
frequency division. Filled with an inert gas with a deionizing impurity.
The cathodes are cold and inactive.
They work in any position.
The countdown is visual, according to the position of the discharge glow;
for 0.1, 5 and 9 cathodes– electric, output
voltage at the cathode resistance. The indication is made through the dome of the cylinder.
The decoration is glass, with a base (RSH5-1).
