Papa Gino Thermometer Temperature Gauge Room & Bath Thermometer (Digital) Bee RBTM002 [Body Size] W7.8 x D2.8 x H9.5cm [Set Contents/Accessories] Main unit, LR44 battery This is a bath thermometer that floats in the bath. When the water temperature is higher than the set maximum temperature, a red light and sound will alert you. (Can be set to 37-40°C.) When the water temperature is lower than the set minimum temperature, a green light will alert you. It also has a count-up function, a clock function, and can be used as a room thermometer. It stands on its own, so it can also be used as interior decoration. There are no instructions or box. There are no major noticeable scratches or stains. The screen is clean because it has only been used a few times. I used it for bathing newborns. After that, it was stored at home. Operation has been confirmed. Batteries are not included. However, please understand that this is a used item.
