Infrared Thermometers: Do They Work Through Glass?

Here’s a video about my Infrared Thermometer and how to use it properly. It will not measure temperature through glass. It is measuring the surface temp. of the glass.
I created this video with the YouTube Video Editor (

Nice test. 🙂

If infra red heat doesn’t go through glass then why do you feel warmth when you stand in front of a sunny sindow? open the lid and test the water surface temp to get an accurate reading.

One more thing! The glass surface reflects some of the (temperature of room or things), so if the meter is point same dot but at different angles, the background heat radiation will change the reading when it is pointed on the glass. (so the water probable is the same temp)

Hey Dan, can you give me some recommendations for tank mates with a Purple Spotted Gudgeon. Nothing scientific, just your opinion.

I actually ordered one off Amazon a while ago. use it very often. Thanks for the info! need a vid on lights, led vs fluorescent ect ect I am debating these right now and you pointing out the heat aspect is another thing to consider. great content.
