Does this measure temperature as well?
No — the 280-HRA is a hygrometer only, measuring humidity from 0–100 %. For combined temperature and humidity monitoring, consider the SAWO 282-THRP or 221-THV thermo-hygrometers available in our store.
Does it require any power?
No — fully mechanical operation, no batteries or wiring needed.
Why is aspen used for the housing?
Aspen is highly moisture-resistant, doesn't release resin at high temperatures, and maintains its shape well under repeated heat and humidity cycles — making it one of the best natural materials for sauna accessories.
