What's a torque multiplier for that an impact gun cant do?

umm, it gives you more torque? A torque multiplier is a reduction gear between the impact mechanism and the fastener socket. A regular impact gun is direct drive with no gearing at the output.

They are used on very large hardware such as pipeline flanges or the nut at the end of the shaft holding a whole jet turbine together.

I've had to use a torque multiplier to torque fasteners down to 1000 plus ft-lbs. It was a manual version with a very long handle. It's for applying serious amounts of torque that you wouldn't otherwise physically be able to do.
 
That is a precision fastening tool used to torque large bolts. It is a direct drive tool not an impact with a torque multiplier to increase the output torque. It uses a motor controller to measure the load and tighten the fastener to a specific value. It also may be capable to measure the Angle and can be programed to torque + Angle tightening strategies.
 
Interesting. I knew about manual torque multipliers that cost around $500 to well over $1,000. The Norbar battery powered version of the OP's link cost about $7,000 and much more in my quicky search.

Regarding the thread title question: I don't believe impact guns apply/measure torque accurately, correct?

correct, an impact does not monitor, measure or control torque. They are best used for hardware removal. If you use them to tighten hardware it is measured in uga-duga's... just make sure you stop 1 uga-duga before it breaks.

just my $0.02
