Bresser Thermo Hygro Quadro NLX - Thermo-/Hygrometer with three external sensorsThe Bresser Thermo Hygro Quadro NLX, like the Temeo Hygro Quadro, offers the possibility to simultaneously measure temperature and humidity at four different measuring points. The three remote sensors deliver the data to the receiving station via 433 Mhz radio frequency, at the same time the receiving station also measures temperature and humidity and thus delivers four measurement results. The main unit requires a power supply unit (included) for operation. For the remote sensors 6x AAA / LR03 batteries are required (not included.).Features:-Clear multi-coloured display time via DCF radio transmission -Date and weekday display -Wake-up function -Four measurement results for temperature and relative humidity -Early prevention of mould -433 MHz transmission frequency -Remote sensors are splash-proof, therefore suitable for outdoor use -Thermal/hygro remote sensor (3x included)-The remote sensors require 6x AAA / LR03 batteries (not included.))
