The Technoline WS9130 comes with a single outdoor temperature that can be mounted on an outside wall with in 100m of the console unit.
This is simple weather station and alarm clock which displays in the inside and outside temperatures plus a simple weather forecast. The minimum and maximum temperatures are also display but be aware they are only displayed in whole figures where as the current temperatures are give to 1 decimal place. The radio controlled clock picks up the signal from the Frankfurt transmitter and gives you automatic accurate time, be aware that the signal is weaker than if the unit used a local UK source.
This is a simple to use and cheap but well made unit with little to go wrong. We recommend it if your main requirement is checking the temperature.
