Keeping track of conditions across several rooms is straightforward with the National Geographic 9070200 thermometer and hygrometer. This multi-location indoor climate monitor shows temperature and humidity readings for four locations at the same time, using the main unit together with three included remote sensors. A clear LCD display presents the readings in an easy-to-read format, while minimum and maximum records help track changes over time. The splash-proof remote sensors can also be placed outdoors, and the base station can be either stood on a surface or wall mounted. With 433 MHz transmission and a 30 m range, it also suits spaces where monitoring damp rooms or changing household conditions is useful.
