Fukuda FRE-203XT - Kit HIRE

The Fukuda FRE-203XT replaces the extremely reliable outgoing Fukuda FRE-208 True Grade laser, to which it shares many of its internal components. It builds upon this foundation to incorporate many new features and improvements which it shares with the other FRE-203X series lasers.

The FRE-203XT is a TRUE GRADE laser where the User can easily input the exact % of slope required, digitally. The instrument will then simply set the laser beam to that slope. This can be in one axis only (single grade) or in two axis X & Y together for dual grading. A radio linked Remote Control with a 100m range makes this quick & easy.

The laser also has plumb up & plumb down, red laser dot beams. By mounting the instrument on its side, called "lay-down" this gives a squaring facility. ie. 90-degree site setting out - a very useful feature.

Constructed with a waterproof housing, an automatic drift system and the facility of radio controlled Dual grade - has made this the Grade laser of choice for Groundworks Contractors. This is another model in the Fukuda range which is extremely robust, having a drop-test specification of 1 metre onto concrete. The top glass "lighthouse" is protected by a metal die cast cover, whilst a robust roll cage adds increased durability.

The FRE-203XT is also suitable for indoor use, where the rotating speed can be reduced to improve visibility of the laser beam by eye; together with a concentrated beam, SCAN facility.

Slope/Grading Overview

General builders, groundworkers, roofers and others often need to calculate slope or at least they must have some understanding of it.

Slope, grade, tilt or inclination can be expressed in three ways:

1) As a ratio of the rise height to the run length (for example 1 in 20) or equally in terms of the fall height to the run length.

2) As a percentage called the "grade" which is the (rise ÷ run) x 100; eg. 1m rise÷ 20m run x 100 = 5% (instead of rise can read fall).

3) As an angle (almost always in degrees)

Of these 3 ways, Slope is normally expressed as a ratio or a percentage grade much more often than an actual angle and here's the reason why.....

Stating a ratio such as 1 in 20 immediately tells you, that for every 20 horizontal units measured, your height changes by 1 unit.

Stating this as a percentage, whatever horizontal distance you measure, your height changes by 5% of that distance. Stating this as an angle of 2.8624 degrees doesn't give you much of an idea of how the rise compares to the run!

Features

The FRE-203XT (auto) self-levels horizontally & vertically, is accurate to +/-2.8mm over 30m & has a 500 metre diameter range using the supplied laser detector.

For site Groundworks use, this is a TRUE GRADE laser. Simply input the slope % directly within the range +10% to -10% of fall. This enables the User to accurately and easily set slopes (grades) in both X and Y axis, as required, with high precision and stability.

The kit includes a Radio Remote Control - to enable you to adjust the rotating speed (for indoor work) and outdoors - to set Grades (slopes), as described above. A very useful feature, which allows control from distance without the laser level being disturbed. Note: Outdoors: set the rotating speed to maximum (600rpm) to give the best operating distance with the supplied detector.

A rechargeable battery pack system is built-in and as back-up, the FRE-203XT will operate on normal alkaline batteries too.

Included in the kit

Fukuda FRD800R Laser Detector (receiver) to extend the range of the FRE-203XT to 500 metres diameter.

Features:

The FRD800R Laser Detector is a highly versatile, well-featured laser receiver for both basic and advanced levelling and aligning applications; designed for general, concrete and site preparation contractors.

It features a digital readout of elevation that provides a numeric display of +/-45mm to 1mm resolution. Accurate measurements can be made without moving the rod clamp, saving time and increasing productivity. The readout is displayed on the large front and rear LCD's, showing exactly how far the elevation is from on-grade. A back-light assists readings in low ambient lighting.

Selectable units of measurement can be displayed to meet your specific application: in mm, cm or inches. A 125mm long red pick-up window, more than double the industry standard, allows quick acquisition of the laser beam. Readings are shown in three ways: via back and front LCD, coloured LED indication and by audible sound, selectable loud/normal/off.

This detector is designed to survive tough construction site conditions, being water and dustproof to IP55.

It can be used as either a hand-held or staff mounted detector for a wide range of construction applications.

Example usage

This TRUE GRADE rotary laser level is primarily designed to be used by Outdoor Groundworks Contractors for:

General groundworks, site 90 deg squaring, footings, foundations, slab laying, grading, land & building drainage and landscaping projects etc.

The FRE-203XT is also suitable for indoor use, where the rotating speed can be reduced to improve visibility of the laser beam by eye; together with a concentrated beam, SCAN facility.

Technical specification

Accuracy:

+/- 2.8mm @ 30 metres, max. operating diameter 500m (250m either side of the instrument).

An accuracy of +/- 2.8mm @ 30 metres is equivalent to 0.09 mm/m and to put that into perspective, the best premium German spirit level has an accuracy of +/- 0.5 mm/m or +/- 15mm @ 30 metres.

Dual Grade facility:

Dual axis X and Y axis up to +/-10% (1 in 10)

Both X & Y axis can be set to give a maximum fall of up to 1m at 10m distance away. (ie. 1 in 10 & +/-10% grade)
