HiLetgo DC 3-5V MAX6675 Module + K Type Thermocouple Temperature Sensor Thermocouple Sensor Set M6 Screw for Arduino

Q: The temperature range is listed as "range: 0¡ãc 1024¡ãc," what is this? i am looking for some that can measrue up to 1000 c.

As the data sheet said for this, the converter allows readings as high as +1024°C, and exhibits thermocouple accuracy of 8LSBs for temperatures ranging from 0°C to +700°C. The output is given in a 12 bit, digital number. In the electrical characteristics, there is a Temperature error for range from +700°C to 1000°C, you should check that as well. This is the link for de data sheet: https://cdn-shop.adafruit.com/datasheets/MAX6675.pdf

Q: Will this screw probe create a watertight seal?

It might if you are careful. The front end seems solid and water proof. The back end (where the wires come out) is not water proof. I am assuming that the front end will be in water. If you were to use a couple of rubbery washers as gaskets, you could keep the back end dry and happy. Personally, I put a plastic sheet around the whole thing.

Q: Are these submersible in water? I have two in a bath, averaging the temperature but I am getting wrong readings as opposed to when they are in the air

The sensor is not waterproof (the wires under the mesh are not covered in any plastics).

Q: From the transmitter temperature range is 0°c - 1024°c, but it's not clear what the temperature range is for the k-type thermocouple. please confirm.

From: https://en.wikipedia.org/wiki/Thermocouple#Type_K Type K (chromel–alumel) is the most common general-purpose thermocouple with a sensitivity of approximately 41 µV/°C. It is inexpensive, and a wide variety of probes are available in its −200 °C to +1350 °C (−330 °F to +2460 °F) range.
