Bath thermometer

Bath thermometer is a simple nursery and home-care tool, meant for checking that bath water stays comfortable for a baby or small child. By our assessment, its real strength is plainness: the reading is immediate, the job is obvious, and there is no app, pairing or learning curve between the water and the result. The trade-off is equally plain, because it is only as good as its own accuracy and the person reading it; a cheap model that drifts or is hard to read defeats the point. In practice it is one of those objects that sits in the tub, gives a quick number or indicator, and then disappears back into a drawer. It belongs to the low-drama end of baby gear, well below fancier monitors and well above guessing by touch alone. The number-free name fits the use: measure the water, check the temperature, move on.
