My Gossen Sixtomat Digital does a nice job too....nice detail is the
sliding dome for incident light metering on top, it also accepts a
second sliding unit, in my case a #87C IR filter. Exposure values 
measured through that filter @400 ASA are compliant with a visible 
metering @12 ASA, my reference for a #87C filter.
The ultimate test (one that I haven't had time for) is such a TTF 
(through the filter) reading under trees....it should be several 
stops higher than the visible reading, as there is much more IR below 
trees than there is visible light....fooled me once with a wedding 
session....all shots were over exposed by at least 1-2 stops.
