Spectra LL300N Plus - Product Overview

Extraordinarily  robust design makes this one of the toughest laser levels in use in the construction industry.

The LL300N is a fully automatically self-levelling laser level - just switch on and it levels itself in a few moments. No bubbles to check or footscrews to turn. The instrument constantly monitors and maintains its level, and will stop rotating and warn the user if it has had a major disturbance which could affect the overall set-up height.

The Spectra LL300N is ideally suited to all groundworks and foundation tasks. The level is very robustly made and is designed to withstand a tripod knockover.

The rotor is protected by a dust and waterproof glass lighthouse encased in a strong alloy frame.

The instrument can be switched to manual mode, whereby the level is no longer self-levelling, and can be set to a slope, such as for drainage work.

The optional RC601 remote  control provides fine slope adjustment contol, on either one or both slope axes; very useful when setting drainage falls.

The LL300N Plus set is supplied with a 5000mAh NiMH rechargeable battery pack and charger.

  • Fully self-levelling
  • Extra heavy duty construction
  • Rechargeable Battery Pack
  • Easy to operate - just switch on
  • 5 Years laser level warranty
