The CL-700A Series models are
shipped ready for use right out of
the box complete with multi-well
insert, AC power cord, insert removal
tool, NIST-traceable calibration and
RS232 interface.
The CL-700A Series range is
covered by an industry leading
3-year parts and labor warranty.
The CL-700A Series models use the
same inserts as previous models, so
you can easily upgrade without the
K-37
need to replace any custom inserts
you may already have. See series
CL-700A, at omega.com/cl-700a
for a list of inserts. For those who
want to run a unit from a PC we offer
Calsoft software which is free for
