Laser & Ultrasonic Distance Measurers

Bosch PLR 30 C laser distance measure

If you have gone through the ordeal of selling your house in recent years, the Estate Agent may well have measured the rooms with a small electronic box of tricks instead of the expected traditional tape measure.  They would have been using one of two things; an Ultrasonic or a Laser distance measurer.  These are highly useful pieces of kit for quickly measuring rooms or distances and many have the additional function of calculating areas and volumes.  For many trades, they are invaluable tools for quickly and accurately working out areas, for example for floor coverings or paint or any number of materials.

So, how do they work?

Ultrasonic Measurers

An Ultrasonic distance measurer uses sound waves to calculate the distance between the tool and the opposing wall or fixture.

There are two different types available on the market.  Firstly the Ultrasonic distance measurer uses a sound beam to bounce off of the opposite wall or item to give the distance from the tool.  Some have a laser point so that the user can see where the signal is bouncing off.  Examples of these are the Stanley Intellimeasure 77-018 or Draper DMSD Ultrasonic Distance Measurer & Stud Detector.  Ultrasonic measurers are slightly cheaper than the alternative laser units, starting at £30-40 but they are not considered as accurate in use and should possibly be described as estimators.

Laser Measurers

Lasers measurers work (as suggested by the name) by bouncing a laser beam off of the wall or item that is being measured.  This has some major advantages, firstly in that it provides more accurate data as it is easier to physically see where the measurer is actually sighted by the position of the laser dot.  Also, a laser is more accurate than the alternative sound beam, so the measurements are again of a higher accuracy.  Laser measurers also tend to have more functions, so they can combine many measurements and make complicated calculations etc, depending on the model.  Although they are primarily designed for indoor use, they can also be used outside, but you may encounter problems in bright sunlight.  Using laser glasses to see the dot will aid you. The Stabila LD520 Distance Laser Measurer has a built in camera with 4 x zoom function so that exact measurements can be taken even when the laser is not visibile.

The Bluetooth capability on the Bosch GLM 50 C enables you to quickly and easily store readings while on the go, while the GLM Measure & Document app lets you create digital floor plans using the assimilated data.

Laser measurers start with the Bosch ZAMO II Distance Laser Measurer, a basic tool which gives basic distances only (up to 20 metres) right up to the top of the range Stabila LD520 Distance Laser Measurer which has a 200 metre range along with multiple functions and features.  There are a wide range of models in between to suit every pocket.  Good models for occasional use are the Bosch PLR 30 C Distance Laser Measurer which has Bluetooth connectivity for downloading and collating your measurements up to 30 metres.  Or alternatively, the Bosch GLM 30 Distance Laser Measurer is a basic professional model, but is made to IP54 standard to withstand the rigours of site work.  Bosch also have the GLM 40 Distance Laser Measurer which as well as being a robust professional tool has an angle or Pythagoras function to measure the height of free standing walls and 40 metres of range.  The Leica Disto range includes the Leica Geosystems Disto D110 Distance Laser Measurer which includes a sketch app with Bluetooth so that you can make the most of your data.  Then we are onto the Bosch GLM 80 Distance Laser Measurer, with a rechargeable battery and angle functions (also available as a kit with a spirit level body for maximum versatility) or the Bosch GLM 150 Distance Laser Measurer, which has many functions including roof slope measurement.

The Stabila LD 520 is a multifunctional bluetooth equipped distance measurer with an integrated camera for visually locating targets up to 200 metres away.

Many distance measurers work in Metric and Imperial but be sure to check the individual model you are interested in as some only work in Metric.  The more expensive the model, the greater the distance they will measure and the more functions they will have.  We know that once you have one of these in your tool kit, you’ll wonder how you ever managed without it.
