yes good way to have bearings in control.
we do it manually now as there is always a watch on the ships. and yes there is an alarm working on it. and the readout is logged in to the big machinelogbook.
so i would opt for a tempalarm/readout on each channel.
however if you have experience with these hybrid recorders they can be used for this purpose.
put the scantime fast but the print time slow.
use alarm switch of recorder to give alarm.
yesterday i used two yokogawa recorders with each 30 channels to have usda certificate to transport fruits to usa.
