Top HVAC Infrared Laser Temperature Sensor Readers Guns
Infrared laser temperature sensor guns are very handy for a HVAC technician. I can’t count how many times I have used mine when I otherwise would have had to of used 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 to. I have worked at a few companies that require temperature reading at the supply and return air on every call.

Some of the return air’s 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 a infrared laser temperature reader is a life saver in moments like that. Getting in and out quickly also saves time, money and work.

Needing a new one I began reading reviews on Amazon on which would be the next best one to get. After reading the reviews I bought the Extech 42515 Infrared Thermometer with Type K Input. It is a bit on the expensive side compared to other units but does what I need it to.

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.

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