Rotary laser level: the site where it changes everything

A line laser projects a line visible over twenty to thirty metres. A rotary sweeps a complete plane and is read with the detector up to 250 m around it. They...

Measuring a height you cannot reach: Pythagoras and angle

From the ground you measure the hypotenuse and the horizontal: the height is the root of the difference of their squares. At 6.00 m from a wall, a reading of...

Measuring an area and a volume with a laser distance meter

A laser distance meter does the multiplying itself: two lengths give an area, three give a volume. In a room 4.20 m by 3.10 m, the stated ±2 mm move the resu...

A laser level under €100: what the price changes

Under €100 you find decent cross line lasers for indoor work. The first things to go are the 360° planes, pulse mode — and with it any prospect of a detector...

Looking after, storing and carrying a laser level

What knocks a laser level out is knocks to the pendulum — and the pendulum only locks if you remember to switch the instrument off before packing it away. Cl...

Run time, battery and USB-C charging on a laser level

The run time of a laser level depends mostly on how many planes are lit. On both our 360° models the manufacturer states about 6 h without naming the configu...

Laser level or spirit level: what accuracy really changes

A spirit level measures a slope over the length of its body, and nothing beyond. Carrying that measurement along piece by piece piles up the errors. The lase...

Méthode

Laser level at the ceiling: suspended ceilings, downlights, track

A suspended ceiling is set out from the laser’s horizontal plane, never from the existing ceiling: that is almost never level. Carry the chosen level onto al...

Méthode

Setting out stud walls and track with a laser level

Mark the axis of the wall on the floor with the laser’s vertical plane, carry it to the ceiling with the same plane without moving the instrument, fix the tr...

Méthode

Stated range, real range: reading the figures

A stated range is measured in good conditions, on a favourable surface, and often with a detector. On site, ambient light, the colour of the substrate and ho...

Méthode

Laser level outdoors: the detector becomes compulsory

In daylight, sunlight drowns the laser line within a few metres: that is not a weakness in the instrument, it is a ratio of powers. The detector picks up the...

Cross line, 3D, 4D or rotary: which laser to choose

A cross line laser is enough for a shelf or a splashback. The 3D covers a whole room with three 360° planes. The 4D adds a second horizontal for the ceiling....
