Our hygrometer thermometer uses an analog system that is not prone to failure, specially engineered to deliver high-accuracy readings, with a tolerance range of +/- 5% RH for humidity and +/- 1-degree for temperature!
This indoor hygrometer is designed with a metal casing made entirely out of high-quality stainless steel and glass with no plastic content, making this hygrometer corrosion-proof, durable and reliable!
This hygrometer analog is mechanically operated and doesn’t require any batteries or liquids to function.
