If you want to be able to get temperature readings from more than one spot, you'll need to do something else. In my case, that was getting a quality (digital) thermometer that uses type K sensors. I have ones that you can submerge into extremely high temperature fluids (easily more than boiling) so I can get a reading from several locations without issue.
I know Bobby_M sells a lot of the combo items, and they're fine for the majority. I just find that thermometers installed into a MLT, HLT or BK just shy of useless. At best, you'll get the reading of what's right there. A few inches in any direction can be a different temperature, but you'll never know. What he sells is significantly cheaper than what I'm using. So, if you want to go the lower cost route, get the fitting from Bobby_M. I would also get (a the very least) a long stem instant/fast read digital thermometer too.
Besides, having the fixed thermometer probe sticking in from the side could be a bad thing for BIAB. Unless your bag will never actually touch it (so it can't rip on it) that is.
