Very AccurateI bought 1 digital and 2 analog hygrometers to go with a new humidifier about three weeks ago. The digital proved almost worthless since it does not give any results if the humidity is below 35% . One of the analogs consistently measures 7% too high. This Taylor 6422 is always accurate at both high and low humidities. It needed no adjustment. All 3 hygrometers were given the salt/water test as well as tested against outside humidity per local Weather Channel. The Taylor 6422 seems ideal for outside use due to its galvanized housing, although we use it inside the house. I would like to have another accurate hygrometer just to compare with in case it gets out of adjustment. Looks like I will just order another 6422.
