    Quote:If you can calibrate it. I have used a number of digital hygrometers to measure humidity in our layer barn in the winter and they all read differently. The one I trust the most is the $300 humidity sensor plugged into our barn's environmental control system. The cheap weather station sensor that is is in there has always reads 20-25% higher.

    Wet bulb may be harder to interpret but if the thermometers are accurate it should be dead on.

    I hear what you are saying. For me, the cheap $20 dollar unit I have works good enough. Incubator holds around 300 eggs (ancient GQF) and as long as the cheap deal reads 40% or better then I'm happy and the chicks hatch.[​IMG]
