Description

The WMS831 model has been discontinued. Please see the WMS-16 Series as a possible alternative or contact our Flow Engineering Department.

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.
