Technical Specification

Accuracy: +/- 1.5mm @ 30 metres, max. operating diameter 800m (400m either side of the instrument).
An accuracy of +/- 1.5mm @ 30 metres is equivalent to 0.05 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: Both X & Y axis can be set to give a maximum fall of up to 1.1m at 10m distance away. (ie. 1 in 9 & 11.1% grade)

nb. The User can single grade from the laser's keypad or for dual-grading applications, the optional radio remote, (RC402N) is required.

Example Usage

Checking/setting elevations, concrete forms, footings, and foundations for small- and medium-sized job.

Basic slope work such as driveways and ramps

Excavations, digging footings and septic tanks
