A Gossen Sixtomat Digital (the smallest digital meter (non-flash!)
from Gossen, called Gossen LunaPro in the US I believe) will read IR 
quite accurately, and I assume many other Gossen meters as well. 
You do however need to mount an IR-filter to it, but the sliding dome 
design of it is such that one can easily fabricate a sliding 
IR-filter, in addition to the dome.
My rule of thumb (400 ASA, +3 for 25, +4 for 87 and +5 for 87C) is 
dead on with metering through any of these filters.
Btw, are there any other meters suitable for fabricating a convenient 
sliding/mounting IR filter?
