Spectra DG813

The Spectra DG813 is a high-accuracy pipe laser designed for precise alignment of drainage and sewer pipelines. With robust construction and extended range capabilities, it is ideal for contractors and surveyors managing medium to large civil engineering projects.

Advanced SmartLine Function: Automatically aligns the beam to the target center, significantly reducing setup time for second-day manhole alignments.
Dual-Display Precision: Large LCD screens on both the laser and the RC813 remote provide clear grade and status updates from the surface.
Superior 150m Communication: Combined radio and infrared technology allows for reliable remote control over long pipe runs or deep trenches.
Extreme Weather Durability: Ruggedized IP68 waterproof housing designed to survive complete submersion and the harshest drainage environments.
Versatile Mounting Options: Fits securely in 100mm (4-inch) pipes and includes accessories for various manhole and “over-the-top” setups.

Spectra DG613

Full Description

The Spectra DG813 Pipe Laser is a premium automatic laser designed to streamline pipe-laying and drainage installation workflows. Built to perform in demanding conditions, it combines a wide self-levelling grade range (≈ -12 % to +40 %) with quick automatic alignment and cross-axis compensation, so you can focus on finishing the job rather than adjusting the laser. A key strength of the DG813 is its bright, highly visible beam with an effective operating range of up to 150 m (≈ 500 ft) capable of being spotted easily even in long pipe runs or deep trench settings without repeated repositioning. With compact sizing, it can be set up into tighter inverts and manholes, making it practical for a variety of pipe diameters and site configurations. The laser features a remote control system (RC803) that supports both infrared (within pipe) and radio communications (for “over-the-top” set-ups), allowing adjustment of grade and alignment from a distance. The large, graphical LCD interface on both the laser and remote equips operators with clear status feedback and simplified menu navigation, reducing training time and error risk. Advanced functions such as Line Set/Check and Line Scan help speed first-day setups and second-day grade checks, while Line Alert notifies the user if alignment or grade has shifted, helping prevent costly rework later. A smart Spot Finder (SF803) included with many packages helps automatically centre the beam on the target and can even calculate the working grade to further streamline setup. Designed for tough site environments, the DG813 is IP68 dustproof and waterproof, capable of continuing operation in wet and dirty trench conditions. It also includes flexible power options with long run times from rechargeable NiMH or alkaline batteries, ensuring extended uptime on busy jobs. With its precision alignment, long operating range, remote control flexibility and rugged construction, the Spectra DG813 is a reliable choice for contractors and survey teams involved in drainage pipe installation, sewer laying, utility trenching and civil groundworks.

FAQs

How does the “Spot Align” function benefit second-day setups?

Spot Align allows the DG813 to automatically search for and lock onto the center of the SF803 Spot Finder. This ensures the laser is perfectly aligned to the previous day’s run in seconds, eliminating the need for the operator to manually adjust the beam from inside the manhole.

Can the DG813 help me find the grade of an existing pipe?

Yes, using the “Spot Match” feature, the laser can calculate the grade of an existing pipe run. By placing the laser and Spot Finder at opposite ends, the unit automatically tilts to find the target and displays the exact grade, making it essential for verifying as-built conditions.

What is “SpotLok” and when should I use it?

SpotLok “locks” the laser beam onto the Spot Finder, preventing the beam from drifting due to extreme temperature changes or high winds. It is particularly useful for “over-the-top” setups where the laser constantly monitors its position to ensure the line remains perfectly stable.

What is the “Line Set/Check” capability?

This feature allows the laser beam to be moved up to 100% (45 degrees) out of the trench. It is ideal for first-day setups, enabling alignment to an above-ground stake or string-line from a deep trench without moving excavators or other heavy machinery.

Is the remote control display the same as the laser display?

Yes, the RC803 remote control features a large, backlit graphical display that exactly mirrors the screen on the laser. This “what you see is what you get” interface allows operators to monitor status and make precise adjustments easily from the top of the manhole.

How does the DG813 handle high-vibration sites?

The unit features an integrated “Line Alert” function that causes the beam to flash if the laser is bumped or disturbed by ground vibrations. This fail-safe prevents pipes from being laid on an incorrect heading, helping to avoid costly remedial work.

What is the waterproof rating for the DG813?

The DG813 carries an IP68 protection rating, meaning it is completely dust-tight and fully submersible. It is built to survive the wettest UK utility site conditions and is even designed to be pressure-washed for easy maintenance after a shift.
