IR thermometer question

[nick brearley <nick@landform.co.uk>]

Any one have experience of this instrument?

I could see it filling a gap, or two gaps in my toolbox. Alternately the 
local RS depot has a Fluke IR thermometer on promotion and their stuff 
seems to be about as good as you get.

Any advice gratefully received.

Thanks.
