Top HVAC Infrared Laser Temperature Sensor Readers Guns
Infrared laser temperature sensor guns are very handy for an HVAC technician. I can’t count how many times I have used mine when I otherwise would have had to use a ladder.

I know getting a ladder is not a big deal and it has to be done all day long but why do it if you don’t have too. I have worked at a few companies that require temperature reading at the Supply and Return Air on every call.

Some of the Returns can be crazy high up, placed on high ceilings which a small ladder can’t reach, causing a whole effort to un-strap a ladder and carry it through someone’s home simply to get a temperature reading.

Having an infrared laser temperature reader is a lifesaver in moments like that. Getting in and out quickly also saves time and money.

I have bought several over the years and they have been a real benefit in many scenarios.

One of the main things I found to look for is what is called the D/S Ratio which stands for Distance Spot Ratio.

A D/S Ratio will number look like this “8:1” or “12:1”.

So, for example, a temperature gun that reads 8:1 can read a spot 1 inches wide from 8 inches away. At eight feet it would need 1 foot of space to get a good read.

There are many good units available with some of our favorite picks below.

As always be sure to read reviews on Amazon, here, or elsewhere to be sure a unit is the right pick for you.
