The LCD thermometer / clock S is a device combination consisting of a triple thermometer for displaying the indoor and outdoor temperature as well as a third temperature range in °C and a quartz clock in 24-hour format. The indoor temperature is measured by the temperature sensor built into the device, while the outdoor temperature is measured by the temperature sensor 825 (item no. 2001) included in the scope of delivery. The additional measuring input is suitable for monitoring a cooling or heating box, for example. For this purpose, we recommend the indoor temperature sensor (item no. 2085), which can be mounted discreetly at the desired location. The quartz clock includes the digital display of the time in 24-hour format as well as a weekday display. The clock is highly accurate and has its own power reserve against power failure.
