Millimeter Display Receiver Vs Standard Receiver

The first thing to note here that we are talking about receivers for Rotating Lasers and not line lasers.  Currently there is not an option for a millimeter display receiver for pulsed line lasers.

A standard rotating laser receiver such as the RedBack LR715 indicates when the receiver is either above the level height of the laser plane , below the laser height or exactly on level.  There are a number of bars that give an indication of when you are moving the receiver closer to level but no more information than that.

A rotating Millimeter display receiver such as the RedBack LR720 provides the same information as the standard receiver but in addition it display how many millimeters above or below the level line the receiver actually is.

Another difference between these two receiver is the size of the reception window.  The LR715 has a  50mm reception window and the LR720 has 110mm which is more than double.  The LR720 will display up to +45mm and -45mm beyond that it will indicate “OUT” meaning its above or below this value.  The LR720 operates with both Red and Green beam rotaing lasers on both class II and 3r.

Why do you want a Millimeter readout?  There are a number of applications that this could be handy for but one is when roughly levelling ground works you may want to work within a plus or minus 10mm tolerance.  This is extremely quick and easy with the LR720 millimeter receiver as it displays this information.  With a standard LR715 receiver you will tend to be working to a 1mm, 3mm or 5mm tolerance depending on the accuracy setting selected for the level line, so will be spending time working to a finer tolerance that you actually need.

Another example would be for fit out applications such as windows.  Here you may find the one side of the window fitting is 5mm higher the the other side so you will instantly know that you will need a 5mm packer for that side.

Many RedBack rotating lasers such as the EL614 range, EGL624 range and DGL digital grade range lasers can be purchased with an LR720 millimeter receiver instead of the standard LR715 you can check out these EL/EGL ranges HERE and the DGL digital grade ranges HERE.

The RedBack LR720 millimeter receiver will operate with most red and green rotating lasers by other manufactures.  For details on purchasing the receiver on its own click HERE
