Characteristic features

  • Robust, user-friendly, easily portable, precise, independent, intrinsically safe, low-OPEX

  • Powered by the battery of the main SVG-6 super explosion-proof light (UNL-01) or an intrinsically safe battery (UNL-02, UNL-03)

  • Battery charging at the lamp room charging table (UNL-01) or with a standard charger (UNL-02, UNL-03)

  • The indicator may be mounted on a bracket fixed to the mine wall, or at a geodetic stand

  • The scope of supply may include a theodolite or not (if mechanically adjusted)
