Description

Valvo ZM1200 Pandicon is a gas-filled cold-cathode fourteen-decade numerical display. Each decade contains digits 0 through 9 plus decimal-point and thousands-separator marks, with common corresponding cathode connections and separate anodes for the fourteen positions. It is intended for pulsed multiplexed operation and long service life.
