Temp guns will give different temps depending on the material they are checking the temp of. Google emissivity tables and check the instructions that came with your gun to see how to adjust this.

Calibration
Pour some boiling water into a styrofoam cup.
Immerse only the insulated portion of the SBS 01T sensor into the water.
Your radio should indicate very close to 212 degrees F if you're close to sea level.
You can also aim your IR thermometer at the surface of the water and take a reading with it to compare the two. Most inexpensive IR thermometers have a 1:1 D/S ratio (Distance to Spot diameter) so for best accuracy you should hold the IR gun no more than an inch or two from the surface of the water.
If you have an accurate digital or dial thermometer to check the actual temperature of the water you can use it as an absolute accuracy check over a range of water temperatures. This would turn up any non-linearity issues as well.
As an alternative, a boiling, 70% mixture of automobile antifreeze will get you closer to the operating temperature of your cylinder head but do it at your own risk. I don't recommend it.
Hope that helps.

+30 degree C difference!!!
The Temp reading is not accurate. It is ok in room temperature. But once I fly and land, and I use my temp gun to check. There is almost +30 degree C difference!!! That's why a can't fly my new GT15hz engine in this week. Once my engine up, it shows overheat. Guys, bring your tempgun with you and check next time you fly.
I have the same problem, the temp gun always show -30 degree C difference, my engine is a nitro OS105
