• This version of Isotope Fob has 3 individual bores to house the tritium, hence the nickname "Triode".
  • The versatile TEC Isotope Triode Fob is designed to hold several glass tritium vials (not included), which will glow continuously for many years without the need to charge it from sunlight or UV light.
  • The Triode can hold several combinations of tritium vials, as each bore can hold either one 3mm x 23mm vial OR two 3mm x 11mm vials. Think of the color combinations!
