Hygrometer

[Farrell]

Del, what brand and model of hygrometer do you use? And about what was the price? Do you recall the stated accuracy of the RH reading in the area of RH and temps. you commonly encounter with your boards? Do you calibrate your instrument? I'm just trying to get a feel for where the accuracy comfort level is for a rebuilder/builder/designer with your experience. Thanks.
