 DUALOG
The 
is a two channel, battery powered logger with audible alarm, but without
display.
The

interval is 1 hour. It stores the worst case values measured during
each logging interval. The time and date of each alarm event or settings
change is recorded in a separate event log.
An additional contact
input may be used, for example, to generate an alarm if a freezer door is
left open.
s
are mainly used in 
systems where a local display, as provided by the  ,
is not required.
