What is the hexagonal part in the middle of the body that has a hole in the middle for?

I holds the cylinder stat together. You need to undo this rand remove the front to wire it

Can it be fitted in a bathroom on pipe work

This is a thermostat for an immersion tank so, NO.

Your text says it is suitable for foam lagged tanks but how does it measure the temperature?

You would have a hole in the lagging just big enough to fit the unit and the sensor on the back of the thermostat would measure the temperature.
