Continuously and simultaneously displays relative humidity and temperature in °F/°C with dual-recall memories. The extra-large, easy-to-view, 5/8” high digits can be read at a glance from as far away as 20’. ABS Plastic housing is chemical- and shock-resistant. Supplied with a wall mount and bench stand, switch to read °F/°C, fast-response, solid-state sensors, and two AAA batteries. Digital hygrometers don't provide quite as much accuracy as hair-hygrometers, but they don't ever need to be calibrated.
