Earl,
We bought the SRT 1000 after looking at after looking at Conceptronics,
Air-Vac & SRT units. While all seem capable of handling the job, the ease of
use of the SRT was one of the factors we liked. From an operator
standpoint, it's pretty straight forward. At the time we looked last year,
both Conceptronics and Air-Vac had interfaces that we felt were more
daunting for our typical operator. No problem for the engineer setting up
profiles, but we don't use them to run the machine <g>. We also talked to
some heavy users of the equipment and got very positive feedback on the SRT
from Intel, HP & Silicon Graphics among others. Of course these were names
supplied by SRT so I'd expect them to be favorable. However in almost 1
year of use I'd have to concur.
Regarding the pickup tube, SRT's claimed accuracy and repeatability is very
good, and we haven't had reason to question it. Placements are dead on as
far as we can tell. While the tube probably is susceptible to damage, the
only time anyone should be handling it, or even near it when extended is
when doing maintenance.
In terms of operation, I actually prefer the convection pre-heat on the SRT
to the IR pre-heat used by Conceptronics, although both vendors have reasons
their's is better. With the number of thermocouples available, we can
pretty accurately reproduce profiles identical to what we'd want to see in
our ovens.
Programming has been pretty straight forward, although as you note, you do
have to edit program files manually. From what I recall, both Conceptronics
& Air-Vac required something similar. Shouldn't be a problem for your
engineer.
Regards,
Rick Thompson
