Hi, I am trying to connect a k type thermocouple to an Arduino uno but I have a problem in choosing the amplifier, if anyone could guide me? I attached a link of the thermocoupe I am using, i would like to ask if MAX6675 works with this K thermocouple?
Thermocouple: https://amzn.eu/d/1ybn9Y6
MAX6675: https://amzn.eu/d/1ybn9Y6
is the connection possible, if not, what other component I could use to make it work?
Hello rwq_01,
You've made a mistake posting the link to the MAX6675, you have in fact repeated the thermocouple link.
The MAX6675 is intended for use with a type-K thermocouple, so it should be satisfactory.
You need to use links readable in English, sowing technical data.
ooh sorry for the inconvience, here is the link of the module I intend to buy, it's just that I am not sure the Thermocouple can fit in the screw holes.
The module you are looking at will do just fine. As to connecting you will need to cut off the Type K thermocouple plug because there is no way it will mate with the MAX6675 module. Another option is your thermocouples come with the standard Type K male plug which as I mentioned you either cut off or buy a mating female socket for and then use Type K extension wire to connect to your module. Note the polarity and on a standard Type K thermocouple the negative pin has the larger diameter and is the magnetic pin. So no, as shown you will not be able to connect the TC plug to the MAX6675 module unless yo0u cut the plug off. That or just open the connector and disconnect the TC wires.
Looking at the images I can't quite tell if the connectors shown are a TC Mini connector or standard not that it matters much. 
Just make sure the thermocouple you buy is the TC you want/need.

Thank you so much for your time, the answer is very helpful.
Anything else you need to know just ask.
