Accuracy +/- 1.6mm per 30m

Who and what is the ALGR designed for ?

The CSTberger ALGR is a completely waterproof automatic laser level with a highly visible laser for both
internal and external work.
With similar features of the ALHV, it has the addition of a manual dial in dual grade up to 10% in 0.01% increments and a higher rotation capability.

Featuring servo motors, the ALGR can automatically self level in both horizontal and vertical modes.

Functionality such as scanning, alignment, grade and rotation speeds is controlled by a remote control.

What functionality does the ALGR have ?

• Automatic Horizontal Leveling - with servo motors.


• Automatic Vertical Leveling - servo leveled when on it's side.


• Plumbing - Automatically plumbs laser dot to the ceiling.


• Squaring - when lying on it's side allows for 90 degree setout.


• String Line setout - when lying on it's side allows string line set out on windy days.


• Vertical plane - sends vertical plane out when lying on it's side for retaining walls etc.


• Scanning - Beam can be scanned in small arcs to give greater intensity


• Rotation control - 0 to 1000 rpm


• Grade - in manual mode dual dial in grade up 10% in each axis in 0.01% increments


• Remote control - controls laser functionality

Calibration

Once shipped from the manufacturer, Accurate Instruments Optical and Electronic Service Centre calibrates all
instruments on collimators and ranges then fits them with the appropriate shockwatch, calibration sticker and
test calibration certificate. Shockwatches indicate to the user whether the instrument has been dropped.

What is the standard package and what are my options ?

A standard construction package usually consists of the laser, receiver, heavy duty aluminium tripod, carry case,
shockwatch, alkaline batteries, calibration sticker and Test calibration certificate.

Optional staves and re-chargeable battery kits etc are also available.

Please phone to discuss a package to suit your requirements.
