What it's made for: owners who like to know the real temperature.

The dial runs 70–250 °F, with humidity on the same face, per the listing. Hang it at head height and away from the heaters so it reads the air you sit in.
What it has going for it
Stainless steel. Stainless steel shrugs off heat and water and wipes clean in seconds.
5 in. The stated size, per the listing.
Infrared cabin: the cabins we list top out around 149 °F (the middle of their stated top settings), so you'll read the lower part of its 70–250 °F dial.
Stove sauna: a stove with stones uses more of the scale. The humidity dial earns its keep there, after a ladle of water on the stones. Either way, mount it at head height and away from the heaters.

Our take
What we'd buy the Defull Stainless Thermometer-Hygrometer for is stainless steel build, with a 5-inch length as a bonus. No buyer reviews yet, so this defull sauna thermometer has to win you over on paper. The catch with the defull: whether it fits depends on your sauna, so measure before you order. We'd pick the Defull Stainless Thermometer-Hygrometer if you want a sauna thermometer for owners who like to know the real temperature; otherwise, put it next to the Andelov Sauna Thermometer-Hygrometer first.
Before you add the Defull Stainless Thermometer-Hygrometer to your cart: check where it will hang, because its scale runs 70–250 °F, and it reads the air around it, so mount it at head height away from the heaters.
