What pipe sizes can the DG813 accommodate?

The DG813 works in pipes from 8 inches to 36 inches in diameter using the included adjustable pipe stand. The stand features spring-loaded extensions that secure the laser firmly against the pipe wall, maintaining stability even in wet conditions. For pipes larger than 36 inches, optional extension accessories are available to expand the range.

How far can I control the laser with the RC803 remote?

The RC803 wireless remote provides reliable control up to 300 feet from the laser, allowing operators to make grade adjustments, power the unit on/off, and check battery status without leaving the work area. This eliminates time-consuming trips back to the laser head and improves safety by keeping workers out of traffic zones and confined spaces.

Can the DG813 be used in wet or flooded pipe conditions?

Yes, the DG813 is rated IP68 for complete dust and water protection, meaning it can withstand submersion and operate reliably in wet trenches, flooded pipe sections, and muddy conditions typical of underground utility work. The sealed housing protects internal electronics while maintaining laser accuracy even when partially submerged.

What's the difference between the DG813 and older Dialgrade models?

The DG813 features an upgraded graphic LCD display with improved visibility in bright conditions, extended battery life (40+ hours vs. 30 hours), enhanced wireless range for the remote control, and lighter weight construction. The accuracy specification remains industry-leading at ±10 arc seconds, but the user interface has been redesigned for faster setup and fewer button presses to change grades.

Job Applications

Sanitary Sewer Installation: Maintain precise fall rates (typically 1-2%) across long runs to ensure proper flow velocity and prevent settling—the Dialgrade interface lets you dial in exact percentages without conversion charts or calculators.
Storm Drain Systems: Achieve steeper grades for rapid water evacuation while maintaining accuracy in large-diameter concrete pipes—the expanded working range handles jobs up to 1,500 feet between manholes.
Force Main & Pressure Pipe: Set dead-level or minimal-grade installations for pressurized systems where air pockets must be eliminated—the ±10 arc second accuracy ensures proper air release valve placement.
Culvert Replacement: Work in confined spaces where the compact DG813 design fits easily, and the wireless remote eliminates dangerous trips through active traffic zones to make adjustments.
Trenchless Bore Operations: Guide auger boring and pipe jacking projects with continuous grade reference—the IP68 rating withstands mud, groundwater, and demanding underground conditions.
Municipal Utility Rehabilitation: Verify existing grades before rehabilitation and ensure new liner installations match design specifications—the Spotfinder provides quick confirmation without removing equipment.
