    I just bought a Humidity Gauge and Thermometer Combo. If I calibrate it, will the Thermometer be affected at all?

    Well, I'm not Vicki, but maybe i can help. :) If you have a soda bottle cap, or even a milk jug cap, use that. You use regular table salt (like is in salt shakers) and fill it up to the top. Take your fingers and drip some drops of tap water onto the salt until the top of the salt is moistened. Place the bottle cap of salt and the gauge (gauges) into a zip lock bag and seal it shut. Wait 4 to 6 hours and then the gauges will be callibrated and can be put back into the tank.

    Will this method work for digital gauges? 'Cause I think that's the kind I have. It hangs on the side of the tank, and reads the humidity and temperature, and then it sends out this little radio-wave kinda thing, and tells the base reader what it is, and it shows up on that. I don't think it has any little screwy bits that would make it so I can change how it reads the humidity.

    When you take them off they should say 75%. If they don't then adjust the nob so it does. I don't know if you have to calibrate electronic ones but do it anyway and make sure it says 75%.
    Good Luck.:)

    Yeah I was wonder about the 2 baggies also. I have the 2 in 1 thermometer and hygrometer, How do you turn their dial? It doesnt look like it comes apart to me.

    I could not find the dial either so I just add 3 degrees to whatever it reads because my gauge is a little low.

    Cause I said to use 2 bags, thats why. LOL Seriously though, just incase one bag had a hole and it affected the reading.

    Ohhh! Now the two bag thing makes sense! :D Do you have to callibrate it every month?
    The first time I calibrated it it read 7% too low, but when I recently calibrated it, it was 3% off. But the second time I left it for more than six hours.:confused:

    Yeah I was wondering if leaving it for more makes the humidity go down. Hmm.

    I dont think time matters. Only reason I mentioned doing it monthly was I lost a lot of crabs caue mine was off and I thought it was fine. I like to be safe then sorry. But it's up to you.

    Do the digital hygrometers stay more accurate? Is it worth it to just get a good one? Id only get a digital if they were more accurate and more reliable.

    Yeah my dial hygrometer was acting weird it went from 70 to 40 in like 30 minutes and I knew that wasn't correct so I bought a digital one and so far it had no problems it costs like 14 dollars though:eek:
