FAQs

What accessories are included in a standard Spectra LL300N kit?

Typically, a professional kit includes the LL300N transmitter, a digital laser receiver, a high-capacity battery pack, and a heavy-duty carrying case. When you purchase or hire from us, we can also provide the staff and tripod for a complete solution.

What makes the Spectra LL300N the preferred laser level for UK concrete contractors?

The Spectra LL300N is the industry standard for concrete levelling due to its fully automatic self-levelling and rugged design. It allows a single person to manage height checks using a receiver, which reduces labour costs and increases accuracy during large pours.

How does the Spectra LL300N handle accidental drops or tripod tip-overs?

This laser features a “hard hat” rotor protection system that can withstand a drop of up to 1 metre onto concrete or a 1.5-metre tripod tip-over. This ensures that simple site accidents do not result in expensive replacements or project delays.

Can I hire the Spectra LL300N for short-term groundwork projects?

Yes, the Spectra LL300N is a staple of our hire fleet. Every hired unit arrives fully calibrated and tested, complete with a receiver and tripod, making it an ideal solution for groundworkers who need professional-grade accuracy for specific project phases.

Where is the best place to get a Spectra LL300N serviced or repaired?

For all maintenance, PQS Survey Ltd offers a reliable service through our network of UK depots. Our trained service personnel have the specific diagnostic tools required to recalibrate and repair Spectra precision lasers to ensure they remain within manufacturer tolerances.

What is the “HI-Alert” feature on the Spectra LL300N and why is it important?

The Height of Instrument (HI) Alert monitors the laser’s position. If the setup is disturbed, the laser stops rotating and alerts the user. This prevents inaccurate readings after a bump or ground shift, avoiding costly rework on site.

Is the Spectra LL300N suitable for use in heavy rain?

The LL300N carries an IP66 rating, meaning it is dust-tight and protected against powerful water jets. This allows you to continue working through heavy rain and muddy conditions common to UK building sites without damaging the internal electronics.

Can this laser be used for basic slope or grade work?

While primarily horizontal, the LL300N features a manual slope mode. When used with an optional remote, the laser can be tilted to match a specific grade. This is useful for setting out simple slopes for driveways, ramps, or drainage falls.

What is the working range of the Spectra LL300N?

The LL300N offers a working diameter of up to 500 metres when used with a laser receiver. This wide coverage allows you to set up in a central location and cover a vast area without moving the tripod, ensuring consistent levels.

How often should a Spectra laser be sent to a PQS Survey Ltd depot for calibration?

We recommend professional calibration every 6 to 12 months. Regular check-ups by our service personnel ensure your measurements remain pinpoint accurate and compliant, especially since internal sensors can be affected by site vibrations and transport.
