Digital Temp Gun

You can also use it as a propane gauge, works better than most of the stick on gauges I have seen for them.

Bought my first one 30+ years ago for $90 (Rayteck) and it found a engine overheating problem in minutes after weeks of trying to solve the problem. I've used it several time today (yes it's still working) checking temperatures in my house. The temp reading that blows me away is pointing it up on a clear day in the summer and getting a reading of -35F degrees... 30,000'. Currently it's too cold and pointed up it's out of it's temp range. I own three and they are one of my most often used tool.

Been using an infrared thermometer for 7 years.
Great for check of tire thread temps, hubs, brake rotors etc.

Distance from object being measured will affect temp (wider vs narrow beam)

I try to hold it 8" from area on each tire/hub so that I can compare the different tires/hubs.
Tire thread....I aim for flat area between threads...two spots
Hubs.....I aim at the transition between drum face and hub and then 2" in from grease cap for two readings
Rotors....on truck I aim just below caliber

Do a quick check at each stop. Sunny side tires/hubs can be higher than shady side. I look for big spread between set on same side.

We have one from Princess Auto, used regularly for tires, hubs etc. When checking tire temps, don't be surprised at variations in temps from side to side (sun/shade) TOOO many variables. Just watch for extreme changes. Seen tire temps as high as 165F. Pavement temp was even hotter.
