My own readings, in pounds. The first point is the first reading I took; after that a point goes on only when a reading comes in 5% or more away from the one before it, which is why the gaps are uneven.

Round, for a car or a boxRoom hygrometers, the smiley face is still smiling at 70 per centTwo small round meters with a black or white bezel, each on an LR44 button cell, shown in a car, beside a fish tank, in a cigar box and in a pet house. Its own panel gives 0 to 50°C and 10 to 90 per cent humidity, and nothing on accuracy. For anywhere a square will not sit. Nineteen room thermometers that also read humidity, from one search and the order export, and underneath them about ten designs. Every listing that explains its smiley face draws the happy band at 40 to 70 per cent, which runs right up to the level where mould becomes likely. Three give an accuracy, and the best of them is plus or minus 5 per cent. Two of the nineteen do not measure humidity at all. Published 4 Oct 2026
