Infrared Thermometer

[Doug&Deb]

I’m wanting to pick up one of these. Which brands are you all using? The prices range from $20 to $200. I’m wondering if the harbor freight cheapie is accurate enough for checking coolant temperature etc.  Seems like this would be a useful diagnostic tool.

I have a Harbor Freight IR thermometer.  it works great.  It picks up slight temp variations on different parts of the engine.  I also use it to find heat leaks in my house in the winter.  It also works to check the grandchildren for fevers.

My work one is a Fluke.

 

I think my personal one is a Sunray?  I dunno had for 20+ years now and I'm not digging it out right now, lol.

 

IR guns can be inaccurate as to a specific value but can be useful for comparisons of similar metals.

 

Used to do IR inspections of the substation at the cement plant I worked at.  Still do them today on electrical connections for work.

 

If you really want to know the details, lol.
