Spectra Precision Red Beam Pipe Laser DG613 FEATURES:New reduced length allows easy set-up even in tight invertsLarge; bright; graphical user interface makes the screen easier to see and use when in or out of the pipe. Same graphical user interface can be seen on the remote – what you see on the laser you see on the remoteSelf levelling range of -12% to +40% over the entire grade rangeCross axis compensation provides a quicker more accurate set-up as the laser does not have to be level in the pipe – place it in the pipe; it levels; you workBright visible beam that works up to 150m (500ft)IP68 protection (dust and waterproof)RC803 remote works via radio 130m (430ft) or infra-red 150m (500ft) for both “over-the-top” set-up and in pipe/trench set-upLine-Set/Check – allows the user to align the laser to the manhole quickly and easily to set direction. The beam will go up to 100% allowing easy alignment at the first day even in short trenchesLine Scan – provides a quick alignment to the center of the target for the second day setupLine Alert- notifies the user if the set-up is disturbed eliminating costly re-work from errorsSPECIFICATIONS:Accuracy±1/16 inch at 100 feet (±1.5 mm at 30 m or 10 arc seconds)Self-Leveling Range-12% to +40%Protection ClassIP68 dustproof and water immersible beyond 1mWeight6.61 lbs (3.98 kg)DimensionsN/AMount N/AWarranty5-yearOperating Temperature-4 to 122 °F (-20 to 50 °C)Tripod Thread5/8 x 11MaterialAluminumDiameter5.3 inches (13.5 cm)Cross Axis LevelingAutomaticColorRed diode laserType/Wavelength600 - 680 nmEntryStep+Go or Digit SelectDisplayPercent; Per Mille; DegreeAzimuth RangeN/ARange-12% to +40%Rechargeable Battery/LifeUp to 40 hoursAlkaline Battery/LifeUp to 50 hoursPower CordN/ADisplayN/AOperating RangeUp to 430 feet above; up to 500 feet in pipesAlkaline Battery/LifeUp to 130 hours Spectra Precision Red Beam Pipe Laser DG613
