Spectra Precision DR400 DIGIROD Laser Detector

Product overview

The Spectra Precision® DR400 DigiRod™ is a versatile, revolutionary tool that eliminates the need for grade rods when checking grades with a rotating laser. The combination of a laser receiver with digital readout, laser distance meter, and built-in tilt sensor provides the information required to take rod-less, accurate grade readings, even at tilt angles up to 30 degrees.

DigiRod Technology

Various grade rods can be emulated including direct elevation rods, cut/fill rods, and indirect reading rods. Units of measure are selectable with the press of a button in meters, decimal feet or fractional inches. This eliminates the need to carry, transport and maintain multiple grade rod types. Elevation measurements can be taken up to 6 meters (20 feet) and the tilt sensor ensures accuracy by automatically correcting to actual vertical distance. The user simply places the laser distance meter spot on the location a grade check is required, picks up the rotating laser beam anywhere on the reception window, and the distance from the ground to the rotating beam is measured and displayed. Errors due to rod math and out of plumb grade rods are virtually eliminated. The rod-less grade checking system also allows for safe trench and excavation grade checking as workers do not have to climb down in the trench or lean over unstable trench edges to obtain elevation readings. Screeded concrete can be checked without leaving marks on the finished surface.

Laserometer Technology

Based upon the popular HL700 Laserometer, the DigiRod functions as a laser receiver and will work with any rotational red beam laser. The receiver has an extra long 127 mm (5 inches) vertical reception range that does not require centering on-grade to obtain a reading. The large LCD screen gives a bright, clear digital readout of elevation that eliminates confusing calculations. An anti-strobe sensor stops construction strobe lights from setting off the receiver. Multiple accuracy setting allows adaptation to meet any job site requirement.

Laser Distance Meter

As a stand-alone laser distance meter, the DigiRod is designed to give contractors a one-person distance measuring and estimating tool to measure remote and difficult-to-reach places such as high overheads, factory interiors, or over water. It can measure up to 50 meters (160 feet) and has an accuracy of ±2.0 mm (±1/16 inch). A continuous measure mode is useful for staking out various distances and a minimum/maximum function accurately measures diagonals and right angles to surfaces.
The versatility, portability, and functionality of the DR400 DigiRod will add value outside of the traditional construction markets and could include applications in surveying.

The DR400 is a combination Laserometer (HL700) with a built-in electronic laser grade rod.

The DR400 combines both functions (receiver and rod) in a handheld receiver sized package.

The DR400 incorporates Trimble HL700 Supercell technology, laser distance measuring technology and angle sensing components to achieve these goals.

FEATURES

As Digirod Laserometer

• Extremely portable, universal system that eliminates the need to carry, transport, or maintain multiple grade rod types
• Increases safety, reducing the need to lean over or go into excavations or trenches
• Increases accuracy, the internal angle compensation system reduces errors and extra material costs due to tilted grade rods
• Increases productivity by always having the correct rod on-hand, and eliminating tool marks on the screeded concrete
• Easy to learn, easy to use - the simple graphical display and bright backlight allow for fast readings in low light
• Works with existing rotating lasers, increasing productivity with a fast payback
• Built-in angle sensing and COMPENSATION up to 30°
• Works with red beam lasers as well
• Radio built into a detector
• Reception Height 5.0 inches (127 mm)
• Operating Range (radius) 825 ft (250 m)

As a Rod Mounted Digital Laserometer

• Digital Readout of Elevation allows faster readings by displaying the exact numerical distance from grade, eliminating the need to move the receiver to get to “on-grade”.
• Anti-Strobe Sensor stops construction strobe lights from setting off the receiver and eliminates phantom strikes for easier identification of true laser beam signals.
• Large 12.7 cm (5 inches) reception height allows faster readings by acquiring the beam quickly and makes it easier to stay in the beam.
• Universal Reversible Clamp for square or oval rods
• Simultaneous elevation LEDs and bright backlight reinforces the elevation display in low light for faster readings

As Handheld Laser Distance Meter

• Increases productivity by one tool having multiple applications
• Increases safety by allowing one person to make accurate readings in difficult-to-reach areas
• Increases accuracy, eliminating issues with sagging or mis-held tapes at different temperatures
