What is the most effective way to measure flame temperature?

[physicskid12]

Hypothesis: The hottest part of the flame can be found at x located just above the unburn gas.


Aim: To investigate how the temperature of a flame varies with the height of the top of the burner.





Help please getting a lot of trouble with method and how to obtain results.

For measuring flame temperature I suggest using a non-contact infrared thermometer. See:

After a quick Google search I saw many selling for less than US$ 50.00. Note: You must select one that has a small “look angle” or small angular resolution. That means it must read temperature of a very small spot in order to measure different points in a single flame. Otherwise you could rig an opaque “pinhole mask” (tinfoil?), move it slowly across the flame, and take measurements. Then you could use any old non-contact thermometer.
