Hi Jake
You could talk to these guys:  - I 
would think they can tell you if it can be tested easily.

My ancient B&B wind instrument has a home made metal vane on it, and 
still works - we tested it today for the first sail of the season, gusts 
 > 25kts.

Ironically, the newest instrument on the boat, a Ray ST60 knot meter, 
never frickin' works - every season once the boat is in the water I have 
to pull the transducer and give it a spin - despite that the thing spun 
freely out of the water.  Riddle me that!!! :-)
