Tempgun?

[Antony]

Saw a few people using these at Teesside last weeked, but wondered where to get one from and how much?

Cheers, waiting on line with anticipation!

I get the feeling you have seen people using the large gun shaped temp guns but they are quite expensive so this might be a cheaper alternative

Might get one myself

We had quite a bit of fun with one of the laser ones at the last race meeting measuring the temperature of some of the racers mid race seeing how when they start racing really close to other drivers their temperature increases!

use temp guns allot in ic on road, had one of those it was ok, for general temp measuring

Thats the one i use and i've had no problems with it.

They are actually quite inacurate

I've heard this before but when you compare two together they read the same.

[Northy]

So they're both inacurate?

100% agree thats why i put general temp measuring, mine is a exergen dx501 not cheap but very acurate

northy is correct in that they are out of calibration, though thay may all read the same, reason i got rid of mine was kept cooking engines

Most of the cheaper ones have emistivity set to approx 100 this means they will only be accurate when pointed at a matt black surface, more expensive ones have adjustable emistivity meaning they can be set to be accurate on all materials but you need to know the emistivity (reflectance) setting of the surface you are measuring.
Do not believe the specs quoted by the manufacturers these are under non real conditions ie being pointed into a black body sources which are used for calibrating them and at a certain distance from the source.
In the real world they are good for comparison readings but not great for very accurate readings.
If you want a more accurate reading measure the temperature of what you want with a thermocouple&Display then adjust the emisitivity (presuming you have a more expensive one) to make the IR Gun read the same you can then use that emisitivity setting each time to get a more accurate reading (also make a note of the distance as that has an effect as well.
