Use pinecil (V1) as a high temp thermoemter?

[Ko1]

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.

The pinecil can read over 400ºC no problem, i wouldnt need more range than 100 to 300ºC, so, anyway i could hook up a thermocouple or something to the pinecil and check the temp in real time? As long as it's kind of accurate (+/-10ºC) it's all i need.
I know it uses a handle sensor and a tip sensor to calculate temp but if i can have the ambient temp kinda controlled for a short amount of time could it read accurately? if so what i'd need to do in order to achieve this? Any help is welcome!

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...

Don't use anything that is used for cooking. but there are videos on YT showing use of a Thin layer of fine sand and a used frying pan that is not used for anything else (see GreatScott) . the fine sand helps even the temps.

There is also a Live volunteer active channel is in discord but has bridge to other comms too. many of the most active volunteers don't check these forums, it is a fluke I happen to be in here today looking for something else.
