Food For Thought When Buying the Ideal Laser Measurer

As an engineer, I’ve done a lot of work on houses that were built over several decades ago, and every square metre has been rebuilt with a vault full of power tools that I use on weekly basis. But a few weeks ago it hit me: I’ve thrown a fair share of broken, fair tools. And as much as I hate to deny this stereotype, as an engineer, I don’t usually open my wallet, unless I’ve done my homework on what I need to purchase. However, in this case, it was obvious that the dog ate my homework. Well, at least I’ve learned my lesson, and now I spend a few extra bucks to buy high quality tools that will serve me good and will last.

I’ve been working in measurement technology for about 20 years, and half of them I’ve spent working with a laser measurer, also known as a LDM. They send a pulse of laser light to the target and then measure the time that it takes for the reflection to return back. When it comes to buying the ideal laser measurer, from my (an engineer’s perspective), you should ask yourself a few question to narrow down your options.

Is the Measuring Done Outside?

If you work outside, a digital point finder or optical scope is a must. Without them, you can see a laser point at a max distance of about 15 metres in broad daylight, and 15 metres isn’t going to cut it. An optical scope is similar to a range finder on old fixed lens cameras – the technology first used to solve the outdoor problem use.

How Often Do You Measure Each Week?

This is about getting value for your money. How many hours do you spend walking around dragging a ladder or a tape to take measurements? What if you don’t have to continue doing that anymore and you get more accuracy in return? How are you going to make better use of that time?

How Much Accuracy Do You Need?

Accuracy isn’t typically an issue if you get your measuring laser from a reputable company. Look for tools certified from the International Standards Organisation (ISO). Granted, it will cost slightly more, but they cost much less than an engineered beam cut 2 centimetres too short because of a low budget measuring laser.

How Much Range Do You Need?

Same thing applies, look for an International Standards Organisation certified measuring laser. Many things can influence range and accuracy, the main ones being target colour and light. ISO certified tools give you specifications you can rely on, not ones achievable only in perfect conditions.

Are You Using Any Design Software?

If you work in programs like Chief Architect or Autodesk, there are several mobile apps you can use to create detailed schematics on site. Some of those programs let you overlay measurements on pictures you’ve taken with your mobile device. Bluetooth-enabled measuring lasers transmit accurate measurements to these applications in real time, as you take them. However, these models are top-shelf and therefore more expensive, so you have to ask yourself the question – what’s your time worth?
