Infrared temperature gun | Joined: Jun 2010 Posts: 1,080 Likes: 1 old hand | OP old hand Joined: Jun 2010 Posts: 1,080 Likes: 1 | Any of you have a infrared temperature gun? What do you like or not like about it? Thoughts on best one to buy for general use and van diagnostics? I don't care about being a few degrees off but would not want to be more than one or two if possible. | | | Re: Infrared temperature gun | Joined: Oct 2016 Posts: 68 journeyman | journeyman Joined: Oct 2016 Posts: 68 | I've never tried one on a vehicle, but I've used them in a manufacturing setting and the one's I've used are extremely accurate. But the gauge is checking coolant temperature while the gun would be checking the surface temperature. I wouldn't expect the 2 to be very close to giving the same results.

I have never had it calibrated, but it is easy to use and is accurate enough for my purposes.

Seems pretty accurate, unless the srfae is highy reflective.
it will read 122f on my aluminum radiator's top tank where a Ktype thermocouple taped to it will read 196f.
If I put a piece of black gaffers tape on the top tank and aim the IR gun there, it reads the 195+f.
They are useful for hunting for the highest temperature, just do not think that the laser pointer is where it is takng a precision reading of that red dot. It will average the temperture within a certain radius of that dot.
They are cheap enough now to be well worth having. | | | Re: Infrared temperature gun | Joined: Jun 2010 Posts: 1,080 Likes: 1 old hand | OP old hand Joined: Jun 2010 Posts: 1,080 Likes: 1 | Thanks ya'll.

Bought it to tune R/C car engines, but use it for all kinds of stuff. Well worth the $50 or so bucks I spent on it. | | | Re: Infrared temperature gun | Joined: Nov 2013 Posts: 3,692 Likes: 32 pooh-bah | pooh-bah Joined: Nov 2013 Posts: 3,692 Likes: 32 | I have a cheap Harbor Freight laser IR thermometer gun I use for diagnosing cooling system problems.
