Use pinecil (V1) as a high temp thermoemter?

[VaZso]

Long story short: Need to do a reflowing of my PS3, don't have the money to pay someone to do a reballing and dont have the tools for it, checking a guide to do reflowing on a normal oven made me want to attempt this, rn all I need is a somewhat accurate oven thermometer but all the ones i checked that are under 20€ are useless for what i can see on the reviews.

I don't recommend you to use your normal oven for reflowing if you still want to cook in it later.
There are a lot of potential harmful materials coming out during this process what you don't want to eat later...
