If you want your cheap IR temp gun checked, I would see if there is a calibration lab close to you that is NAVLAB or A2LA approved for IR temperature calibration as a discipline. They would probably charge less than a hundred bucks to do a check on your gun. (if you don't want a calibration cert with the service, more if you want one) The larger problem is that you must determine the spot size at the distance you are using the gun and what emissivity the gun is set to. (cheap ones typically 0.95) The calibration lab can check your gun with a calibrated black body and tell you how close it is. Your relative measurement should yield useable data if you measure the same material at the same distance at varying temperatures. (even if you cannot change the emissivity of your device to the proper setting for the material being measured) Do not expect highly accurate measurements with a cheap gun (+/- 20 F over 70 to 400F) Relative temperature change is what you really want to know anyway.
And yes, I am a Metrologist with over 32 years of experience. My cheap 20 dollar IR temp gun works pretty well within the previously described conditions.
