remote surveillance of
environmental conditions in
RH520 shown smaller
than actual size.

such as computer server rooms,
clean rooms, laboratories,
museums, warehouses, or any
remote facility.
View and record temperature and
relative humidity. Data points can
be transferred to PC via RS232
serial port for further analysis.
The remote (detachable) probe
senses the ambient conditions
while the LCD graphs and
provides numerical representation
of the readings. Programmable
audiovisual alarms alert the user
when ambient conditions reach
alarm presets. The optional alarm
module permits automatic relay
switching when alarm presets
are reached.
The software is a full-featured
program that allows you to set up
all data logger functions including
sampling rate, logging duration,
start mode, logging mode,
and high and low temperature
alarm values.
