•
Three Transmission Channels Selection
•
Case Can Be Wall Mounted Using Built-In Hanger
The WMS831 wirelessly transmits
outdoor temperature, humidity,
quantity of rainfall, wind velocity
and direction from the exterior
sensors to the display station from
up to 100 m (325') away. The unit is
expandable up to 5 outdoor
temperature/humidity transmitters,
for climate control of remote rooms,
e.g. children’s room, wine cellar, or
greenhouses. Monitor indoor
temperature and humidity with
comfort level indicator of indoor
climate. View LCD weather forecast
with symbols and trend of
atmospheric pressure. Also read
absolute and relative atmospheric
pressure with 24 hours history and
bar graph indication of atmospheric
pressure, temperature or humidity
for the last 24 hours.
The unit includes a radio controlled
clock with different alarms and
snooze functions with displays of
date and day of the week
(6 languages). LCD shows time of
rising and setting of sun and moon
with indication of moon phase.
Wind chill factor and dew point with
programmable alarms for
temperature and storm conditions.
Data logging software and cable
are included.
