[QUOTE="Badwolfe, post: 1981671, member: 113003"] You are testing temperatures far out of the range of most IR guns that people will buy. When we are talking about lower temperatures found in a viv even setting an incorrect e value will be minimal because we are not talking large numbers here. Temperature varience is going to be a lot more when using number's in the 100's comapred to numbers in the 10's of degrees. Most people use one of three things - rock, wood or some sort of cloth based hammock. All of these fall in the high 80's to mid 90's on the emissive scale. Even reading something thats .80 on the emissive scale would record a temp that is accurate to within less than 1 degree on a IR gun set to 0.95 Can't say I've encountered many people who use a shiny polyurethane coating on any fixtures. In fact its recommended to use a matte sealant on home made artificial rocks, etc.... a shiny one can result in burnt retpiles due to heat reflection off the shiny surface..... IR thermometers are specifically designed to record surface temperatures and give you a reading (normally within a second) and can update that reading every second usually. Digital thermometers with rubber / plastic probes often sold in the reptile trade measure ambient air temperatures and do not measure surface temperature - they are just measuring the temperature of the air being heated up by the emitted heat. They also require long time periods to even start recording a temperature close to accurate - usually 5 minutes or more and take considerably longer to record variences. The surface temperature of the material emitting the heat can be significantly higher than the ambient air temperature being heated by that material. Put your hand above a bulb dome reflector and feel the temperature of the air then put your finger on the dome itself and see how hot it is. Thought I'd use that example seeing as we are using extreme examples. Probe thermometers are perfect for monitoring the temperature gradient of the air within a vivarium but, in my personal opinion, when it comes to measuring actual surface temperature they are inferior to IR thermometers which are specifically designed to measure surface temps. Like I said each to their own when it comes to how people wish to record their basking spot temps and people should make sure they are fully versed in the correct use of any equipment they use for their pets. Otherwise its like buying a T5 UV and installing it 4 inches above your basking spot! [/QUOTE]
