Mini Markers incorporate a Betalight Gaseous Tritium Light Source (GTLS) which provides a reliable, safe and self-powered source of continuous light output. No battery or charging by ambient light is required during the lifetime of the product. GTLS comprise a sealed borosilicate glass capsule which contains a tiny amount of gaseous tritium, the power supply for the device. Beta-particle radiation (ie. electrons released by the gaseous tritium as it decays) is harnessed to energise a phosphor coating on the inside surface of the capsule, causing it to glow. As a sealed source, they are non-emissive and operate at a very low energy level. Every Betalight source light is manufactured and tested in accordance with the UK MOD Defence Standard 62/4. GTLS containno moving parts and, because the unit is continuously energised, an off/on switch is not required. They will remain energised for more than 10 maintenance-free years, even during extended periods of complete darkness. Betalight devices can be used in any environmental conditions, even under water, and in temperatures ranging from -40º to 80ºC. They are suitable for operation in Zone 0 hazardous areas.

 

There are two installation options available to the user. The “Mini”, which utilises both base and canopy as a single unit and is suitable for surface fixing by (two) screws, double-sided tape or contact adhesive. Secondly, the “Micro” comprises only the canopy piece and is suitable for fixing using double-sided tape or contact adhesive. The Micro marker offers a very compact footprint, enabling the units to be installed in tight spaces and on miniature items. When using the Micro configuration, the base piece is discarded.
