If I buy a probe/tap combo thing like your picture above, will it still work with the readout device I have? Or would it in all likelihood be calibrated wrong? I could test it with a kettle of boiling water, but I think it's better to find out before I buy it.
Question 2:
Assuming any probe/tap combo like that which I got would be calibrated wrong for my readout thing, what I was trying to ask in OP was is there just the tap portion I can buy somewhere then put my probe into that empty tap? Or maybe I just get a bolt and drill a hole in it that fits then use the bolt as a tap?

If accuracy and response time are important, the sensor needs to be in the coolant.
The readout is designed for a certain type of sensor. If it is designed for a Type K thermocouple, an RTD will not work. The readout instructions will tell what type of sensor will work.
Threaded sensors usually have pipe threads. Pipe threads are cut on a taper so that the sensor will fit tight when screwed in. Pipe thread sizes can be confusing - a 1/4" NPT thread is about 1/2" diameter.
The tap thing you asked about is called a thermowell. They are expensive because they are used in difficult industrial applications. You would be better off to get the right sensor.
