    This is just my experience so far but I feel obliged to share this.

    Right now in my Brinsea incubator I have 4 hydrometers.

    1 Brinsea Wet Bulb registering 45% (ACCURATE)
    1 Flukers $5 analog reading 45%
    1 Flukers dual digital reading 25%
    1 Flukers dual digital reading 37%

    See the pattern???

    I was wondering how the wet bulb one works. So its pretty accurate?

    I like analog devices as they are usually solid. Digital devices can be great IF manufacturers don't cut corners, which they all do now a days, resulting in a product with high variances in parts that add up.

    Looks like you got a good deal on that hydrometer!

    Edit, a wet bulb vs non wet bulb is basically a temp measurement on a regular thermometer and a thermometer that is literally wet inside of a sock or shoe lace. Take the difference in temp and there are charts to figure out what the relative humidity is based on temperature differences at particular dry bulb temps. At least this is what I remember.

    So you need to do conversions on wet bulb, correct?

    PC where did you get the $5 Fluker?

    I'm assuming the wet bulb is accurate. I can't be sure.

    Silkiechicken, I like analog devices too. Sometimes the simplicity is better.

    I purchased the analogs at a pet store. You can usually find a $10 package
    with a Hydro and Thermo together. I believe I got these at Petsmart or Petco.

    Yes, you have to do a conversion. It's easy. You just look at a chart.
