Infrared thermometer gun

[Global BTC]

I have one of those listed on Bitmit:

So I am thinking about buying one those thermometer guns with a laser pointer for measuring card temps, and probably annoying my cat.
...
Any advice on what to search for, what to avoid...or a good brand maybe?

To measure exact core temp you need to use hardware thermo-sensor on chip.
All another ways will give you incorrect reading.

Consider painting a small target area flat black. Shoot temps on the same flat black spot every time and you are good to go even on metal.  Just a thought.

You will have consistency to see deltaT. Man.

Or maybe a sticker or some McGyver-tape?

I was very tempted to buy the one from Global BTC (just to use BTC ) but I wanted one with adjustable emissivity.

Anyway, I finally decided on this Fluke 62 MAX+

Info here

I found also some nice Testo guns, but a bit more expensive.

Or maybe deep pink......

I'm scouting my suppliers for an adjustable one right now.

Really sorry man, already bought that one

philips: No problems, I hope you are happy with what you bought

I'll be listing the same model Bicknellski mentioned (BT-GM700) on Bitmit soon. I think it's very good for the cost. My price will be a little bit lower than from Aliexpress.


Variable emissivity from 0.1 to 1.00 will give accurate readings.

guess i'm late to the party, i was going to reccomend

as a non contact i've had a good experience with and

for one with a temperature probe(the decibel measure is also good for finding dying fans before they get too far gone)

The cheaper ones usually have very wide optics, meaning you get the reading from a huge area in front of the gun. Mine has 2 lasers to indicate the exact circle of reading. Just remember the one laser models don't really read from the pinpoint laser dot, but a circle around it with a diameter changing with the distance. You'll get better readings if you know your gun and it's specs.

just to add to his point the one i posted says 8:1 spot size(manual is on it's page along with +/- temp deviation information)
