Saw this while looking for an owner's manual for my cheap Harbor Freight temp gun. Just a layman here but quite fascinating on the principles. Hats off to you guys who did their math homework years ago!
One of the best presentations ever! Just fix the writing of the letter Sigma, cause it is written differently :) Anyways this video has helped a lot!!! :D Thank you!
@Apogee Instruments Inc. So does water on canopy improve transpiration along with stomatal conductance (bottom right @27:31)? And what is described by mol/ms at 27:31, mols of what, any gas particle? Thanks for this information.
Shocks. Thank you lord and thabk you sir. Im doing my thesis related to agriculture and Some of your explanation are so helpful to me. Godbless sir and goodnight. I will play this again tomorrow
So 'hot' shiny gold, say 400K, radiates giving a temperature of near 0 Kelvin, as it has a e value of near 0. On the other hand high reflective - high albedo - snow has an e value of near 1. Something is either very wrong with emissivity understanding, or quantum mechanics and thermodynamics physics is wrong - where all matter above absolute 0K radiates EM radiation. Physics is right. I have the answer; what is it worth? Radiation theory is incomplete and needs updating.
Hi, Blair. Dr Bugbee is at a conference in Amsterdam at the moment. He doesn't actively monitor our TH-cam account so I have emailed your comment to him for a reply. I'll post it here when I get it. Thanks.

Great Video to learn the most important things about infrared radiation and non-contact temperature measurements!
Absolutely like it!

at 12:11, what if we have sun radiation?
This is a great help, thank you very much!
Great video
What leaf tempreture range is best for cannabis
at 12:11 of the video, T_measured should be higher than T_surface
Very good video! Thanks
Very nice presentation. . .
Thanks Sholagberu. We are glad you enjoyed it!

Hello
Dr. can one use this experiment on a free-standing wall?.
thank you
what wavelength do the sensors emit?
See 18:00
Great video thank you very much!
thank you!
Brilliant. Thank you.
Hi, my 2 laser gun, the bottom one has gone off. Any ideas how to check or replace diode? Model HT-817.
lmao you people
@@DasAntiNaziBroetchen what is IMAO???
it means laugh out of my ass bommer
Emissivity 6:00
Thank you
Thank you....
I had no idea this problem existed.
