DR400 No-staff Laser Receiver - Product Overview

The Spectra Precision DR400 DigiRod eliminates the need for a survey staff when checking levels on site with a rotating laser.

The all-in-one combination of laser receiver with digital readout, laser distance meter and integral tilt sensor enables the operator to take accurate level readings instantly anywhere on site.

The DR400 DigiRod Receiver emulates a measuring staff or rod of up to 6m long. The user simply aims the laser measuer at the ground point to be level-checked and raises the receiver into the zone of the level`s rotating laser. There is no need to centralise the receiver on the laser beam - the DR400 will correctly calculate the height and level wherever the laser beam strikes the receiver receptor.

The internal electronic tilt sensor in the DR400 DigiRod automatically corrects the calclated heights and levels when receiver is held out-of-plumb. 

A preset benchmark height can be entered if required, and then all heights will be from site datum.

If required, the DR400 DigiRod can be used with a measuring staff as a standard receiver, with up/down arrows in the display and a bleeper for high/low/on target. In the standard receiver mode the DR400 digitaly displays the height difference from on-target, up to 50mm from above or below the  on-target height.

The DR400 DigiRod can also be used as a stand alone laser distance measurer with a range of up to 50m


Measure ground levels and excavation depths anywhere on site.
